market research

Vacuum pumps, pressure gauges, and vacuum valves combined make up the biggest expense on the bill of materials for semiconductor OEMs. The semiconductor industry consumed almost $2.7 billion worth of vacuum subsystems in 2020, with over 60% supplied by vendors based in Europe.

Sales of process power and reactive gas subsystems for semiconductor manufacturing equipment are on track to achieve a compound annual growth rate (CAGR) of 23% between 2016 and 2021 – far outpacing the critical subsystems industry average of 16.4% due to multiple positive factors.

After logging record shipments in the first quarter of 2021, the silicon wafer industry may need to start greenfield projects as soon as this year to boost capacity over the next two years as market demand and average selling prices continue to improve.

The global economy has started down a gradual path to recovery from COVID-19 in recent months as the world continues to combat the virus. Yet one sector – semiconductors – has shown impressive growth powered by a transformation hastened by the pandemic across industries ranging from education and work-from-home to healthcare.Semiconductor sales increased 12% in September to mark a second consecutive month of double-digit growth, and year-to-date semiconductor receipts as of September jumped 5.5% compared to the same period in 2019, according to SIA/WSTS.While this upward trajectory is encouraging, it pales compared to 2020 semiconductor equipment billings growth, with results from SEMI showing worldwide global chip equipment billings in September soaring to a new high of $7.6 billion this year. During the first nine months of 2020, aggregate equipment billings logged a 23.6% rise compared to the same stretch in 2019, surpassing $51 billion. Better still, the total semiconductor equipment market in 2020 is on track to beat the previous high of $64.5 billion set in 2018.Investments in China, Taiwan and Korea are fueling the chipmaking equipment spending surge. With big domestic and international fab projects in the works, China this year is projected to become the world’s largest capital equipment market for the first time, surpassing Taiwan, which will follow at a close second. Korea will rank third in equipment investments. Taiwan and Korea growth will come on the strength of equipment spending for manufacturing leading-edge semiconductors.Equipment billings in North America and Europe declined year-over-year as the automotive and industrial sectors suffered the heaviest blows from COVID-19. Investment momentum in both regions is expected to pick up in 2021 after automotive production recovers to pre-pandemic levels while factory automation will boost industrial demand.For more information about monthly equipment billing trends by region and equipment segment, please see the SEMI Equipment Market Data Subscription.Clark Tseng is director of Industry Research and Statistics at SEMI.

Global business conditions continued to improve through October although the rate of improvement slowed a bit as pandemic concerns increased (Chart 1).Electronic Equipment Shipments RecoveringThird-quarter world electronic equipment shipment growth showed a big improvement over the second quarter but was still down an estimated 1.4% compared to the same quarter in 2019 (Chart 2).Based on regional electronic equipment shipment data, October 2020 sales were up 3.5% versus October 2019 and up 6.1% sequentially versus September 2020 (Chart 3). As the traditional autumn busy season winds down, the key impediment to a strong recovery is the rising COVID-19 infection rates, especially in the United States and Europe. The world awaits the deployment of a much-needed vaccine.Semiconductor Growth May be EbbingSemiconductor chip shipments continue to increase but their global rate of growth has leveled off to mid-single digits (Chart 4). Wafer foundry sales growth also appears to be peaking (Chart 5), pointing to slower chip growth in coming months.SEMI Equipment ShinesSemiconductor capital equipment shipments continue to outshine both electronic equipment and semiconductors. Third-quarter 2020 SEMI global sales were up a whopping 31% compared to the same quarter in 2019 and up 16% versus the second quarter of 2020 (Chart 6). SEMI equipment shipments are definitely outpacing semiconductors on a 3/12 growth basis (Chart 7).SEMI Outpaces Electronic Supply ChainGlobal electronic supply chain growth is improving but the semiconductor sector is clearly the winner this autumn (Chart 8).Looking Forward, Pandemic Spread is Biggest WorryBusiness conditions definitely look brighter. Even stronger growth is likely if we can get COVID-19 under control.Walt Custer of Custer Consulting Group is an analyst focused on the global electronics [email protected].

MEMS and image sensors are shining stars in the chip industry as technology companies worldwide accelerate innovation in the fight against COVID-19. The tiny devices are behind advances in areas of electronics ranging from thermal imaging and faster point-of-care testing to microfluidics-based polymerase chain reaction (PCR) tools and techniques to detect SARS-CoV-2.SEMI recently spoke with Yole Développement analysts Dimitrios Damianos and Chenmeijing Liang about MEMS and imaging sensors market trends and how microelectronics-enhanced technologies are supporting the worldwide push to contain the spread of COVID-19.For additional insights on the technologies, join the SEMI MEMS Imaging Sensors Summit, held for the first time at SEMICON Europa, 12-13 November 2020 in Munich, Germany. Registration is open.SEMI: Despite the global pandemic, the MEMS and sensors market is still growing and is one of the healthiest industries, not only in Europe, but globally. What is driving this growth?Damianos: MEMS have been continuously evolving from the first sensors that were measuring pressure and acceleration to rotation sensing and visible light management followed by light sensing beyond visible and the expansion to ultrasound and multi-spectral. Now we are heading towards an era where we want to sense every aspect of our environment, with more processing and eventually analytics bringing more quality to the data.COVID-19 has impacted various global markets in very different ways. While automotive, mobility and civil aviation have suffered, the impact on telecommunications and medical has been positive. The effects on the consumer, mobile and industrial markets have been moderate. Moreover, COVID-19 is changing the perception of the current global supply chain in manufacturing, potentially leading to more localized value chains and further regionalization in order to minimize similar risks posed by the pandemic and the first lockdown.SEMI: Who are the main MEMS players based on your research? Damianos: For MEMS players, the picture in 2019 was not the same as 10 years ago, when Texas Instruments (TI) and Hewlett-Packard (HP) were leading the scene, with Bosch and ST Microelectronics following, all at comparable revenue levels. Now, Broadcom and Bosch lead with almost $1.4 billion in revenue each, and the rest of the MEMS key stakeholders compete in the $400 million to $600 million league. Microphone players profited from the voice interface adoption trend, while players active in MEMS for mobility and smartphones suffered slightly due to weak end-system demand.SEMI: What scenarios can we expect for each market with regard to the impact of COVID-19 on MEMS for 2020? Damianos: For 2020, at Yole Développement we expect the consumer market to contract slightly by 2.6%, with the automotive market to dip by 27.5%, and defense and aerospace by 20.5%. For the defense market, no major effect is expected, as all major programs still run for the year. The market may experience some slight delays in deliveries due to supply chain and logistics problems. However, sensors integrated in commercial/civil aerospace applications will suffer due to the general paralysis of the air travel industry. On the positive side, telecommunications could increase by 4.7%, medical applications by 10.6%, and industrial by 11.5%.Due to the global pandemic, some types of MEMS have spiked in demand this year. For example, demand for thermopiles and microbolometers used in temperature guns and thermal cameras has increased because of the need for contactless monitoring of people’s temperatures. Moreover, microfluidics for DNA sequencing and real-time polymerase chain reaction (PCR) diagnostic tests for detecting COVID-19 are gaining market relevance, with the latter serving as a premier method of detecting a bacteria or virus on the molecular level with high degrees of accuracy. Furthermore, pressure and flowmeters in ventilators will grow because of huge demand by hospital intensive care units (ICUs).SEMI: What growth trends do you predict for the long haul?Damianos: In the longer term, we expect global MEMS volumes to almost double, from 24.4 billion units in 2019 to 50.8 billion units in 2025, with a 13% CAGR during the same period. The global MEMS market could reach $17.7 billion in revenue by 2025.We see a trend to more wearable devices integrating a lot of sensors but also a move to a more consumer-oriented healthcare. Moreover, everything related to voice interfaces and voice/virtual-personal assistants (VPAs) will continue to see strong growth, increasing demand for MEMS mics with better quality and high-fidelity voice capture. MEMS devices are shifting to higher accuracy, ultra-low power, embedded intelligence and possibly some bio-compatibility for medical applications.MEMS players will try to escape the commoditization cycle and deliver more value by increasing the value of the data, either grouping many sensors to create sensor hubs or by adding processing, algorithms and software. Industry players are employing strategies such as adding extra processing close to the sensor (e.g. Knowles) or ameliorating the use cases of their applications of their clients (e.g. Bosch or ST). AI on the edge seems very alluring for extra value acquisition, with many startups already working on it. Some examples include always-on-sensing (Aspinity in collaboration with Infineon, Syntiant), echolocation (IMERAI) and predictive maintenance using inertial sensors (Cartesiam). This will be the next pit stop for MEMS technology for sure. SEMI: The CMOS Image Sensor (CIS) is a cornerstone technology in the development of devices powered by machine sensing and artificial intelligence (AI) for applications such as advanced driver assistance system (ADAS). CIS powers many of the ongoing revolutions in new technical products and use cases. What is the status of the image sensors industry? Liang: Last year was exceptional with a combination of high demand and high prices due to capacity limitations. Q4 2019 went way above the forecast, and, in the end, the CIS industry reached $19.3 billion for the full year. This year, we think it will return to normal, and, despite the pandemic impact, we expect significant growth in the range of 7% to 12%. Last year’s 25% year-over-year (YOY) growth was the highest we’ve seen over the past decade. Mobile still dominates the marketplace for CIS with 69% market share. Two markets, computing (8%) and consumer (5%), are adjacent to the mobile market but progressively losing ground due to the smartphone disruption.Security, at 6% market share, will probably be the second largest CIS market in the future. Although this is an area of excellence for the emerging Chinese players, unfortunately, they could be hit by the current trade war. The automotive market did very well from 2018 to 2019 because of the numerous applications recently developed for ADAS, viewing, and in-cabin applications. Lastly, the industrial camera applications benefited from large investments in automation, especially in the semiconductor and automotive industries, but here again many uncertainties remain as these markets will reshuffle in the post COVID-19 world. SEMI: Which CIS markets are most susceptible to seasonality and the impact of COVID-19?Liang: According to our quarterly CIS monitor, automotive and security were both negatively impacted by the pandemic beyond what we expected in terms of seasonality. For computing, the situation improved just prior the lockdown. Q1 got a positive impact with high sales results for laptops and tablets, but no significant impact was seen for security equipment. For automotive, the demand for cameras was very high in Q1, which is seasonally normal, despite the decrease of car shipments that followed later. The automotive CIS market in 2020 should remain relatively flat compared to 2019 due to the higher attachment rates of cameras despite the lower number of cars produced. Consumer and industrial segments dropped in Q1, which is typical early in the year.The next five years might be a bit slow, and although we forecast growth for the next year, in the future the market share will be lower in mobile. In fact, mobile CIS growth will fall below the CIS growth average, but we will see an increase of market share for the security, automotive and industrial segments. The CIS market could reach $28 billion in 2025.At first, COVID-19 had a limited impact on the production side, as factories in China are usually closed for the New Year holiday, when the pandemic started. While supply is currently recovering, we still consider the limited impact on demand. Smartphone production for 2020 will be down 6%, but camera shipments for mobile should increase about 10% this year. Another positive trend for the mobile market is optical fingerprint implementation. Currently, high-end Android phones use this kind of technology. For 2023, we estimate optical fingerprint technology revenue to be over $1 billion.The roadmap for the automotive market is driven by camera proliferation. We’ll see 10 cameras per car and more for some high-end vehicles. Increasing demand for safety and convenience will mean more cameras per car in the future. With a strong attachment rate, the market average in automotive is around 2.0 cameras per car nowadays, and we expect the market average to reach 3.5 cameras per car in 2025. In security, Charge Coupled Device (CCD)-based cameras are nearly out of the market, as CMOS-based IP cameras are most important now.SEMI: What are current key technology trends?Liang: 3D semiconductor technology is the hot topic. CIS wafer staking technology is indeed at the center of the CIS technology race. Future applications could be AI analytics or recently developed applications on new types of CIS. So far, we have seen the introduction of variants of the CIS pixel. Global shutter (GS) and indirect Time of Flight (iToF) were recently introduced, and now direct time-of-flight (dTOF) pixels are being used in high volume. 3D semiconductor technology is a bonanza for the industry, as it allows to pack more value in a single chip. While the surface of silicon is still increasing, additional silicon is added through stacking.With COVID-19 still a problem, the endpoint for smartphones in 2020 remains uncertain. The short-term impact for CIS will be slower growth with respect to the 25% YoY of last year. The downturn in car production will be mitigated by an increased attachment rate for automotive cameras. The security market will also help maintain CIS growth.For more insights, see the following reports: Status of the MEMS Industry 2020 3D Imaging and Sensing 2020 CIS Market Monitor Q2 2020 Dimitrios Damianos is a technology and market analysts at Yole Développement covering MEMS, Sensors, Photonics and Imaging.

With all major global electronic equipment OEMs having now reported their third quarter financials, we estimate that combined equipment sales increased 0.4 percent in 3Q’19 versus 3Q’18 and 2 percent sequentially from the second versus the third quarter of this year.

There is a glimmer of light at the end of the tunnel. But most electronic industry time series will likely struggle at least though autumn.

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.
