Business and Markets

This year, SEMI ISS covered it all – from a high-level semiconductor market and global geopolitical overview down to the neuro morphic and quantum level. Here are key takeaways from the Day 1 keynote and Economic Trends and Market Perspectives presentations.In the opening keynote, Anne Kelleher from Intel pointed to the huge growth of data, with fabs collecting more than 5 billion sensor data points each day. The challenge, Kelleher noted, is to turn massive amounts of data into valuable information. Moore’s law is not dead. New models of computing benefit still from Moore’s law and advances in Si/CMOS technologies for conventional, deep learning, neuro morphic and quantum computing.With customers expecting continual improvements in applications, the question is whether the chip industry is moving fast enough to meet these expectations, Kelleher said. A broad supply chain, equipment and materials innovations, and attracting the “best of the best” college graduates to fuel innovation is key, she said.In the economic trends session, Nicholas Burns (ambassador ret.) from Harvard University pointed out that we will see a major shift in power. The U.S. will remain the major world power over the next 10 years, but we will see a major shift in power in the next coming decades as the gap with countries like China, Russia and India continues to narrow.Duncan Meldrum from Hilltop Economics said that we are passing the peak growth of economic cycle. He warns that a more likely outlook is that a global growth recession is developing. Although semiconductor MSI growth will see a noticeable slowdown in 2019 and 2020, the semiconductor industry is still healthy over the longer term.Bob Johnson from Gartner sees demand shifting from consumer to commercial applications with higher ROIs and budgets. AI, IoT and 5D are the major enablers. He sees structural changes in the semiconductor industry especially for memory but also for Moore’s law with increasing costs and fewer players.The DRAM markets shows volatility and NAND market may be negative in 2019 but non-memory are expected to accelerate mainly because of increasing content and some price hikes.Overall Gartner expects good long-term growth with a CAGR (2017 to 2022) of 5.1%, outpacing 2011 to 2016 CAGR of 2.6%. After a strong 2018 with 13.4% revenue, he forecasts a slower 2019 with 2.6% growth followed by a 8% growth in 2020 and negative growth rate in 2021.Andrea Lati of VLSI went “Back to fundamentals” in his presentation about the industry. VLSI sees a downside bias due to slowing global economy, tariffs, and trade wars. Future drivers are data economy, cloud, AI and automotive.As memory leads the 2019 slowdown, analog, power, logic and other sectors remain in positive territory. VLSI lowered its semiconductor equipment forecast for 2018 from 20% (Jan. 2018) to 14% (Dec. 2018) but increased its sales outlook from 8% to 15% in 2018. VLSI expects revenue to slow into the first half of 2019 but increase to over 4% in the second half of the year, resulting in total 2019 drop of 2.7%. Semiconductor equipment sales are expected to drop from 14% in 2018 to -10% in 2019.Michael Corbett of Linz Consulting, covering wafer fab materials in the years of 3D scaling, sees these as good times for the industry. His outlook for wafer fab materials is bullish based on strong MSI and because wafer fab materials suppliers are getting bigger because of M As.In the Market Perspective session, Sujeet Chand of Rockwell Automation pointed out that as more and more data is generated, the problem is how to get value of all the data collected. There is a need to create the right architecture for machine learning and AI and big data is increasingly being replaced by contextual/structured data. He expects Industry 4.0 to drive foundries to become smaller, more flexible and more productive.In the Technology and Manufacturing session, Aki Sekiguchi of TEL addressed process challenges in the age of co-optimization. The semiconductor industry continues to expand, driven by massive growth of interconnected devices, with heavy demand for processing power and storage. He expects an exponential increase of data from about 40ZB in 2018 to 50ZB in 2020 to 163 ZB in 2026.Major technologies such as DRAM, 3D NAND and logic are dealing with scaling challenges. The density of DRAM (Mb/chip) is plateauing according to 2015 to 2020 trend data, with DRAM is in need of EUV. Memory capacity demand is leading to increasing layers and higher aspect ratios that is concern for 3D NAND and mainly for plasma etch. With Logic already implementing 3D structures, it appears to be in a solid position. Buddy Nicoson of Micron talked about his 50 years in the industry and looked ahead to the next 50. The anchors – quality, cost, scale and speed – won’t change. It has been a great journey so far with unprecedented opportunities and challenges ahead of us. We are getting into a convergence (specialization, integration) and solution-based phase. We will see some inflection points in the coming years, with the best yet to come.Christian G. Dieseldorff is senior principal analyst in the Industry Research and Analysis group at SEMI in Milpitas, California.

Region’s Fab Capacity Expansion Picks up PaceUnwavering in its drive to build a strong, self-sufficient semiconductor supply chain, China plans more new fab projects than any other region in the world from 2017 to 2020, and its expansion of fab capacity recently picked up pace on the strength of new foundry and memory projects from both domestic and foreign companies, according to SEMI’s 2018 China Semiconductor Silicon Wafer Outlook report. China’s installed fab capacity is forecast to grow at a 12 percent CAGR from 2.3 million wafers per month (wpm) in 2015 to 4 million wpm in 2020, faster than all other regions.Well known for its semiconductor packaging prowess, China in recent years shifted its focus to front-end semiconductor fabs and a few key material markets. In 2018, the region’s surge in fab investment thrust it past Taiwan as the second largest capital equipment market in the world, behind only Korea. However, China’s semiconductor manufacturing growth faces strong headwinds. Chief among them is the tight supply of silicon wafers over the past two years due in large part to the sector oligopoly’s firm control of global production, with the top five wafer manufacturers accounting for over 90 percent of market revenue. In response, China’s central and local governments has made the development of its domestic silicon wafer supply chain a key initiative, funding multiple silicon wafer manufacturing projects.According to the 2018 China Semiconductor Silicon Wafer Outlook report, many of China’s domestic silicon suppliers capably provide wafers 150mm in size and smaller. And the while the region lags peers in 200m and 300mm processing technology and capacity, strong domestic demand and favorable policies have fueled progress in 200mm and 300mm silicon manufacturing with some Chinese suppliers having reached key large-diameter manufacturing milestones.However, it will take these new suppliers several years before they can meet capacity and yield requirements of the larger-diameter silicon wafer market. Company plans and announcements indicate that by the end of 2020, total silicon supply capacity in China will reach 1.3 million wpm for 200mm, possibly leading to a slight oversupply, and 750,000 wpm for 300mm.China’s equipment suppliers, particularly crystal furnace vendors, are also investing in the development of 300mm wafer manufacturing, and domestic tool suppliers have developed most of the necessary tools for wafer manufacturing, except for inspection.While China’s silicon wafer suppliers continue to lag international peers in manufacturing capabilities, the region’s silicon manufacturing ecosystem is maturing and becoming better integrated. The sector’s growth is driven and accelerated by significant domestic market demand and favorable policies.About the China Semiconductor Silicon Wafer OutlookSEMI’s 2018 China Semiconductor Silicon Wafer Outlook is a comprehensive research report with a Microsoft Excel® workbook containing in-depth analysis of China’s silicon wafer manufacturing ecosystem as it relates to the global semiconductor wafer industry. The report covers the latest developments in China’s silicon wafer supply chain, including details on the rise of China’s silicon manufacturing, polysilicon, and silicon wafer-related equipment companies. The report also examines policies, funding and their implications for China’s silicon wafer supply chain.Clark Tseng is director in Industry Research and Statistics at SEMI.

Orders for critical subsystems evaporated in the second half of 2018 after a very strong start to the year. Subsystems suppliers have been left with depleted order books after OEMs accumulated large inventories as the market for wafer fab equipment cooled off. Although overall critical subsystems revenue growth for 2018 is forecast to come in at +5% YoY, this year has been a tale of two halves with a bumpy ride for the critical subsystems supply chain along the way.The year started very strongly with overstretched OEMs switching from a “just in time” ordering strategy to panic buying and over ordering critical subsystems “just in case” as they battled to keep up with equipment demand from chipmakers. However, falling memory prices and technology push outs from major chipmakers in Q2 saw a sharp reduction in capex and demand for equipment. The whiplash effect through the supply chain has been severe and critical subsystems suppliers running at full capacity were unable to stop fast enough.Comparing inventories of vacuum processing OEMs (major consumers of advanced critical subsystems) and critical subsystems suppliers, warning signs for subsystems suppliers were apparent after the Q2 quarterly earnings reports. After OEM inventories surged in Q2, critical subsystems supplier inventories spiked in Q3. The overproduction of subsystems leading to this spike suggests that the OEMs had been promising orders to subsystems suppliers but turned off the buying as they too struggled to shift their own products earlier in the year. Suppliers of highly customised subsystems such as vacuum valves and power supplies were particularly badly hit. Whereas other subsystems such as vacuum pumps, which can generally be repurposed on other tools or applications, have fared better as the oversupply can be consumed by a wider variety of applications.The bad news does not appear to be finished for subsystems suppliers as Q3 OEM inventories as a percentage of revenue remained at historically high levels, which is a concern in the short term. Nevertheless, the underlying drivers for the industry remain strong and there is light at the end of the tunnel as major fab building projects in Asia appear to be continuing without delay – a promising sign that chipmakers are still intending to increase capacity. There will be a lot of empty fab shells and upgraded clean rooms ready for equipment installations at short notice if required, ensuring that orders for equipment and subsystems will pick up again soon. Although 2018 will appear in the historical data as a flat, if not slightly positive year, it does not quite reflect the bumpy ride that has been experienced by the supply chain along the way.For more information about VLSI Research and Critical Subsystems, visit www.vlsiresearch.com/public/csubs/.

Automobiles have become an even more important segment for MEMS and sensors as carmakers integrate more chips for propulsion, navigation, and control into their designs. However, these advanced functions and their crisp rate of adoption have fragmented the sourcing of automotive chips. IHS Markit’s Jérémie Bouchaud provided a closer look at and outlook for this key market at the MEMS and Sensors Executive Congress in late October in Napa. Following are key takeaways from his presentation.Autonomous and Electric/Hybrid Vehicles to Drive MEMS Market GrowthThe automotive market, approaching 100 million vehicles produced annually, is approaching $6 billion, dominated by MEMS and silicon magnetic sensors for chassis and safety, and powertrain applications. Going forward, the market growth will be in autonomous vehicles and electric/hybrid vehicles. Because the penetration of electric and hybrid vehicles is much higher than that of autonomous vehicles, it has a larger available market, particularly for sensors. Each of these markets has its own dynamics.For example, the electric and hybrid market has historically relied on a significant number of traditional, or non-semiconductor sensors, but new sensor technologies are vying to address multiple sensing needs. The most important limitation on demand of autonomous vehicles is the overall market penetration: IHS Markit expects autonomous vehicle production to reach 10 million at most by 2030.Production of Electric and Hybrid Automobiles Now Growing at Fast ClipProduction of electric and hybrid vehicles is in a rapid growth phase, and IHS Markit expects penetration of such vehicles to reach 50% of the automotive market by 2030, up from 3% in 2016. The core functions of charging and power inversion require, among other capabilities, current, temperature and position sensing. Historically, many of these functions have been handled by non-semiconductor devices, for example negative temperature coefficient (NTC) thermistors for temperature sensing, devices that appear to be strongly positioned. In other areas, semiconductor sensors are competing with traditional devices.For example, silicon magnetoresistive devices are going head-to-head with inductive devices for position and Hall effect sensing. Sensing requirements are also likely to evolve over time, particularly as battery systems become more reliable and robust. While some automakers are looking to sensors to monitor pressure or gas leaks from batteries, battery makers are more focused on maturing the systems and reducing the need for monitoring.Autonomous Vehicles Drive New Source of Demand for MEMS and SensorsThe movement towards automated driving has created a new source of demand for MEMS and sensors, with advanced driver assistance systems driving faster growth than the historical powertrain applications. Currently available vehicles are at Level 2 (partial automation), with multiple cameras and radars. Level 3 vehicles (conditional automation) are likely to enter the market next year, adding driver monitoring cameras, LIDAR systems and, potentially, microbolometers or other night-vision systems. Level 4 and 5 (high and full automation, respectively) will add vehicle-to-vehicle communications and other systems, but are not likely to be widely available for several years.The autonomous vehicle market, while smaller overall compared to electric/hybrid vehicles, provides a more attractive opportunity for MEMS devices, particularly in LIDAR systems. LIDAR and other sensing/surveying systems are at the heart of autonomous vehicles, and MEMS devices are in demand for the critical beam-steering function. However, demand for image and other sensors will accelerate as the higher levels of autonomy are rolled out.Automotive Drives Extremely Diverse Set of Applications for MEMS and Sensor MakersThe automotive market presents an extremely diverse set of applications for MEMS and sensor makers. Some companies have developed broad product portfolios and compete in multiple applications. For example, TDK offers NTC thermistors as well as MEMS and silicon-based sensors. Semiconductor companies such as Infineon are competing in MEMS and with silicon-based sensors such as magnetoresitive and Hall effect.The growth in demand for image and radar sensors used in ADAS, as well as magnetoresistive and Hall sensors in EVs, means that the center of gravity in automotive markets is likely to shift from MEMS over the next several years – a fundamental change, Bouchaud cautioned, that will put automotive sensor suppliers focusing solely on MEMS at risk.Paul Semenza is a consultant in SEMI Industry Research and Statistics.

IC design has emerged as the largest semiconductor sector in China, with 2017 revenues of $31.9 billion generated by about 1,380 companies. At the same time, China’s fabless segment has risen to third in global rankings with about one-tenth of worldwide sales.Most of China’s fabless segment produces the logic chips that are key to defense, telecommunications, finance and other industries important to the region’s national security interests and its independence from U.S. and other international suppliers. Investment in fabless logic continues to be the top priority in China’s Phase 2 investment. In mobile, China made meaningful progress through HiSilicon and Spreadtrum, both fabless design houses.In 2017, HiSilicon and UNISOC (formerly Spreadtrum), China’s two largest domestic IC design companies, were ranked in the global top 10 of fabless companies, though most Chinese IC design companies are small, with revenues under $1 million. Working with domestic smartphone makers, both companies have carved out a strong presence in logic and, in particular, the communications and application processors that power data centers and Internet of Things (IoT).Despite their rapid rise, China’s AI accelerators and cryptocurrency ASIC suppliers have yet to appear in China’s top 10. However, we expect their aggressive roadmaps and early adoption of leading-edge process technologies to propel them into the top 10 in the near future. As illustrated in the figure below, an examination of the competitiveness of China’s semiconductor segments reveals that the close proximity of China’s fabless companies to the region’s electronic systems makers plays to their advantage, though access to IP and leading-edge process technologies is a barrier to their growth in the near term. A key barrier to China’s foundries is their limited ability to develop leading-edge process technologies and strategic relationships with top international fabless companies. Most leading international fabless companies rely on customer-owned tooling (COT) and design tools for design. As the approach takes time to develop, it will not support China’s aggressive goal and timeline to independently meet domestic IC demand. Instead, China has been disciplined in executing its strategy to acquire valuable IP and leading-edge technologies by aggressively partnering with international fabless design leaders and pursuing deals with market leaders and laggards. The initial entry point for Chinese fabless companies was the low-margin consumer applications dominated by Chinese suppliers, giving them considerable control over demand. In addition, Chinese companies have aggressively hired top talent from abroad and grown the skills of its engineering workforce to sustain innovation. China will likely free itself from its reliance on non-Chinese developed manufacturing process technology and EDA design tools.China’s semiconductor design growth, concentrated in the Pearl River Delta (see figure below), is fueled by national and local investment programs. SEMI August 2018 The Pearl River Delta, which includes Xiamen, Quanzhou and Shenzhen, is establishing itself as China’s IC design, system and application hub. Domestic and international companies are eligible for investment provided they are established or investing in one of the four regionshat are home to various sectors of the electronics and semiconductor supply chain. Access to large investment funds, coupled with China’s infrastructure build-out, is a strong supporting force to drive the growth of top-tier domestic fabless companies. For its part, the Phase 2 of China’s National Investment Fund targets investments of RMB 150 - 200 billion ($23 billion - $30 billion) in IC design. The growing domestic consumer base and infrastructure investment will drive opportunities for China’s fabless companies over the next decade.To learn more about the latest development on China IC Industry, and get a sample of the China IC Ecosystem Report, visit http://www.semi.org/en/china-ic-ecosystem-report.China IC Ecosystem Report covers the rise of China’s IC industry, national and local government policies, public and private funding, and their implications for China's IC supply chain.

Electronic EquipmentGlobal electronic equipment production is in its traditional “fall busy season” as the consumer driven end markets ramp up for the holiday season (Chart 1). Both normal seasonality and organic growth are driving this year’s upturn. September 2018 electronic equipment output was up almost 10% over the same month last year. This actual year-over-year growth when overlaid on an autumn seasonal upturn is providing a nice end of year finish. Source: Custer Consulting Group based on regional data American Electronic Supply ChainChart 2 shows the annualized (12/12) and 3-month (3/12) growth of the U.S./North American supply chain. Aside from the computer sector, all the domestic end markets are expanding driven by defense, electromedical, instruments and control equipment. Total domestic electronic equipment orders were up 8.2% in August 2018 versus August 2017.For components there are clear indications of slowing growth. Printed circuit board orders eased to a +2.7% expansion rate on a 3-month basis and passive component orders contracted 0.2%.The semiconductor industry appears to be coming down from its recent bubble as domestic SEMI capital equipment growth cooled to +3.8% and chip shipments to North America also slowed (to a still respectable) +15% on a 3-month (3/12) basis.

This is not regional production but rather consumption -- an indication of regional demand. It effectively measures electronic assembly activity by area. In August over 62% of the world’s chip value was consumed in in Asia/Pacific with another 8.1% used in Japan. Europe consumed 8.5% and North America 21.9%.

Part 1 of this article discussed the Memory Inventory Cycle Index and compared it with memory device sales and memory fab equipment investments. This article, the second of the two-part series, illustrates how the Memory Inventory Cycle Index starts to weaken before memory sales of the top three memory suppliers decline. It also shows how the Memory Inventory Cycle Index peaked in the fourth quarter of last year along with YoY growth rates for both memory sales and memory fab equipment investments.In addition to the weakening signaled by the Memory Inventory Cycle Index, memory suppliers are facing headwinds in the form of tariffs as mentioned in Micron’s most recent earnings call. The U.S.-China trade dispute could reduce Micron’s profitability; China granted a preliminary injunction to prevent Micron’s Chinese subsidiary from manufacturing and selling in China this July. However, it is very difficult to quantify the risk the tariffs pose to the future of the memory market.On the other hand, the YoY growth rate of semiconductor sales according to the World Semiconductor Trade Statistics is closely tied to China’s manufacturing sector as shown by the Purchasing Managers Index (PMI) New export orders and Orders in hand sub-indexes. Figure 3 shows that as the growth rate of new exports and order backlog slows, the YoY growth rate of semiconductor sales will be adversely impacted. As the largest consumer of semiconductors in the world, China will bear the brunt of the slowing market. Figure 3. Memory Inventory Cycle Index China manufacturing sector PMI’s sub-indices * RemarksChina PMI’s sub-indices are on the basis of the data published by NBS (National Bureau of Satistics of China). Also those data were calculated based on 12MMA (12-month moving average) to minimize seasonal fluctuation. The YoY growth rate of the 3-month moving average of semiconductor sales in China alone, China and Asia Pacific, and all regions showed additional declines in July (Figure 4). Monitoring the Orders in hand and New export orders sub-indices for China and China’s semiconductor consumption and WSTS sales revenue in China can help track the risk of trade disputes. Figure 4. YoY growth rate of semiconductor sales revenue in China and Asia Pacific * Remarks1) Regions as defined by WSTS’ Bluebook.2) Sales revenue were calculated based on 3MMA (3-month moving average value). A review of the relationship between the Memory Inventory Cycle Index, semiconductor sales, and memory fab equipment investment growth rates suggests we have passed the peak in the current cycle. However, bear in mind that the Work In Process (WIP) to Finished-goods inventory ratio has sharply increased since 2017 as shown in Figure 5. The increase in WIP inventory could be attributed to the increasing technical challenges associated with 3D NAND stacking and DRAM scaling. As a result, the proportion of finished-goods inventory in total inventory remained low until the second quarter of 2018, possibly implying that memory demand remained healthy in spite of the contraction modeled by the Memory Inventory Cycle Index. Figure 5. The proportion of finished-goods inventory in the total inventories * Remarks 1) All inventories data from 3 companies’ financial reports were calculated based on 4-quarter moving average.2) Total Inventory accounts for the sum of Finished-Goods, WIP, and Raw materials inventory.3) Company data complied by SEMI. The Memory Inventory Cycle Index has entered a period of contraction, which is supported by Micron’s weak guidance for its fiscal first quarter of 2019 (September to November). The outlook for memory sales and memory fab equipment investments reported by WSTS and SEMI, respectively, also suggests that a market correction is underway. While the low proportion of finished-goods inventory does not threaten the market yet, it should remind industry observers to view high WIP inventories with caution. Unlike past inventory cycles, the high inventory levels could burden the memory market in the absence of sustainable demand.Sungho Yoon is a senior market research analyst in Industry Research and Statistics at SEMI.

Micron, one of the top three memory semiconductor companies, reported solid results for the fourth quarter of fiscal 2018 (June to August) to extend a multi-quarter string of strong growth. However, the company’s mediocre guidance for the current quarter has raised concerns that memory demand will start to slow.To shed light on this super memory cycle, which began in the second half of 2016, this article examines correlations among the top three memory suppliers’ sales revenue, quarterly inventory levels, World Semiconductor Trade Statistics (WSTS) market data, and memory fab equipment investments reported by SEMI.The Memory Inventory Cycle Index, which is based on financial data reported by Samsung, SK Hynix and Micron, is the difference between the year-over-year growth rates of sales (or shipments) and inventories. The index explains business cycle fluctuations such as expansions and contractions, trending up in expansions and declining in contractions. Figure 1 shows both historical Micron sales (blue dotted line) and the quarterly Memory Inventory Cycle Index (black solid line). To minimize seasonal fluctuations, both were calculated based on a four-quarter moving average of sales and inventories. Figure 1. Memory Inventory Cycle Index Compared to Memory Sales* Remarks1) Memory Inventory Cycle Index = YoY growth rate of memory sales revenues - YoY growth rate of memory total inventoris value on a four quarters moving average.2) Calculated memory sales and inventoris are based on Samsung, SK Hynix, and Micron public announcements.3) South Korea Won were converted to US$ based on the quaterly average value released by FRED.4) Companies’ sales data were calculated based on 4-quarter moving average.5) Company data complied by SEMI. As shown in Figure 1, the Memory Inventory Cycle Index has been declining since peaking in the fourth quarter of 2017, mirroring the previous two contractions – in 2010 and 2014 – in which memory sales slowed or stagnated after four quarters of the index decline. Accordingly, if this relationship holds between the Memory Inventory Cycle Index and sales, Micron’s sales will slow in the coming quarters and is consistent with Micron’s guidance for the current quarter. Moreover, the index suggests that the sum of three companies’ sales (the solid red line) will exhibit a similar trend of decreased growth in the coming quarters, which will impact the annual growth rate of global memory sales.WSTS recently increased its 2018 forecast for memory sales to 30.5%, up from 26.5% projected in June of this year. However, the 3-month moving average of memory sales shows that memory sales already increased by 48% YoY in the first half of the year, which means growth is expected to be lower in the second half of the year. Other signs pointing to a weaker end to the year include front-end equipment investments by the top three memory suppliers. SEMI is modeling an annual increase of only one percent for the year for these suppliers, with spending down 23% in the second half relative to the first half of the year.Figure 2 shows the historical trend of the Memory Inventory Cycle Index, the YoY growth rate of memory sales, and YoY memory fab equipment investments. The Memory Inventory Cycle Index increased faster than memory sales and fab equipment investments in the past two cycles. In the most recent memory cycle, these three indexes are moving in tandem, each peaking in the fourth quarter of 2017. Figure 2. Memory Inventory Cycle Index, Memory Sales and Memory Fab Equipment Investments* Remarks1) Both sales and memory fab equipment investments data were calculated based on 4-quarter moving average to minimize seasonal fluctuation.2) All data are from SEMI, except memory sales (WSTS) While overall memory sales continue to be strong this year, memory ASPs have shown signs of weakening right after the inventory index peak. NAND flash ASPs have been trending downward since the first quarter of 2018. With the recent inventory correction and short-term CPU shortage, DRAM ASPs are expected to soften in the fourth quarter of 2018. The looming memory market slowdown has memory makers adjusting their capacity expansion plans for the rest of this year. Some new capacity additions, especially for DRAM, have been pushed out to 2019. The memory inventory cycle index has to some extent foretold the slowdown of the memory market. In the second and final part of this article, we will discuss the correlation between the Memory Inventory Cycle Index and China’s semiconductor sales and Purchasing Managers Index. We will also look at the increasing level of memory inventory in the past few quarters and its composition including Work-in-Progress and Finished goods.

Process power and reactive gas subsystems for semiconductor manufacturing equipment have grown at a CAGR of 21% since 2013. The segment growth is considerably above the critical subsystems industry average of 9.5% and is attributable to higher demand for vacuum processing equipment over the period.Process power and reactive gas subsystems now account for approximately 12% of all expenditures on critical subsystems used on semiconductor manufacturing equipment, up from 7% in 2013. The main driver of this exceptional growth has been the rise in vacuum processing steps (deposition and etch) during the manufacturing processes of both logic and memory devices. Most deposition and etch processes require an RF generator to provide a plasma energy source in the chamber, increasing demand for tools with power subsystems such as RF power supplies and matching networks.Multiple patterning and the advent of 3D NAND in high-volume manufacturing have significantly increased the number of deposition and etch processing steps and, in the case of 3D NAND, longer and more difficult etch processes are requiring a wider range of power solutions. Further analysis shows that 3D NAND has been the principle growth catalyst, with the total share of power subsystems going to memory applications increasing 8 percentage points since 2013. Memory applications now account for almost half of all power subsystems demand in 2018. Interestingly, investigation of power subsystems by tool type reveals that a clear majority of power subsystems (60%) find their way on to etch tools with only 40% on deposition tools. This can be explained by the fact that more delicate etch processes can require multiple RF power solutions per tool, whereas deposition does always use plasma energy sources, for example in thermal deposition processes.Despite the staggering growth performance of the power subsystems segment over the past five years, we expect the growth rate to moderate significantly in the run-up to 2023. Now that 3D NAND has been adopted in high-volume manufacturing, we expect the rate of increase in vacuum/plasma processing steps to slow down. The introduction of EUV also has the potential to taper demand for vacuum processing equipment. However, it is not expected the reverse the trend as multiple patterning techniques will still be needed in conjunction with EUV to achieve the desired improvements in device density and performance. The future growth trend for power and reactive gas subsystems is forecast to be in line with the critical subsystems industry average at approximately 2.0% CAGR until 2023.For more information about Critical Subsystems and VLSI Research, please visit www.vlsiresearch.com/public/csubsJulian West is a technical and market analyst at VLSI Research Europe.

Outsourced Semiconductor Assembly and Test (OSAT) service providers experienced strong growth in 2017, but will this growth continue? In the last few years, OSAT growth has been driven by shipments for packages found in smartphones, but this market is slowing. What will replace it? Growth in power devices is strong and electronic content in vehicles is increasing. Will OSATs participate in this growth? Many OSATs have plants dedicated to automotive package assembly and will see continued growth. Growing demand for connectivity everywhere, called IoT, is generating large amounts of data, creating the need for more servers and datacenters. The adoption of Artificial Intelligence (AI) across a broad range of applications is driving demand for high-performance packages, but will this assembly take place at the OSATs or foundries? In the third and fourth quarters of 2017, growth in cryptocurrency provided unanticipated revenue for a number of OSATs. Given that the most well-known crypto mining companies and the biggest mining pools are all based in China, several OSATs, including major Taiwanese and Chinese service providers, experienced revenue growth in 2017 directly attributed to the assembly of ASICs in flip chip scale packages (FC-CSPs) and GPUs in flip chip ball grid arrays (FC-BGAs) for the cryptocurrency market. However, the first and second quarter of this year has seen decreased demand for GPUs and ASICs for this application. The assembly of packages for cryptocurrency slowed considerably in the first half of the year and therefore can’t be counted on to add as much to the revenue base as in the previous year. Going into the latter half of the year, the demand for Crypto ASICs is expected to pick up as new generation of 7nm chips will drive new investment and replacement cycle while crypto-mining GPU will see a further decline. Three of the top 10 OSATs, Jiangsu Changjiang Electronics Technology (JCET), Tianshui Huatian Technology (Huatian), and Tongfu Microelectronics (TFME), are based in China. China’s share of the top 10 OSATs’ revenue increased from slightly less than 23 percent in 2016 to more than 25 percent in 2017, and this trend is expected to continue. Crypto-related packaging and test business has certainly contributed a big portion of the share gain. Major OSATs such as TFME and Tianshui Huatian plan expansion in their plants and they expect to fill this added capacity in a broad range of packages. Huatian’s new Nanjing plant will include assembly for memory packages. TFME plans to set up a plant in Xiamen, Fujian Province to provide bumping, wafer level packaging, and system-in-packaging (SiP) services. Tracking the capabilities of OSATs is increasingly important. SEMI and TechSearch International have introduced a new Worldwide OSAT Manufacturing Site Database that provides listings of OSAT facility locations and package and test options in each factory. This database indicates the specific packages offered at each location. Finding plants that offer automotive qualified assembly is also possible with the database. Companies that offer bumping and wafer level packaging are identified. Over 120 companies and 300 facilities are tracked in this database covering both OSAT packaging and test facilities. For additional information about this informative database, please visit https://discover.semi.org/osat-database-registration.html E. Jan Vardaman is president of TechSearch International, Inc., and Clark Tseng is director of Industry Research and Statistics at SEMI.
