fab equipment

Policymakers are increasing semiconductor manufacturing capacity to strengthen supply chains and meet growing demand for semiconductors through robust incentive packages totaling hundreds of billions of dollars. This global effort hinges on semiconductor manufacturing equipment (SME).

China’s semiconductor sector has exploded to become one of the largest in the world and match the region’s prominence as the biggest consumer of chips. From 2015 to 2020 alone, revenue of China’s integrated circuit (IC) industry expanded at a rapid clip of 20% CAGR (RMB) to $128 billion.

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/.

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.

SEMI Releases latest update to World Fab Forecast with adjusted semiconductor revenue consensus for second-half 2018 and 2019 Global semiconductor revenue in 2018 is now expected to reach $473.8 billion and clock a growth rate of 15 percent, a significant upward revision from the 7.5 percent expansion (to $442.9 billion) forecast at the start of the year by six research and investment forecasts tracked by SEMI Industry Research and Statistics (SEMI IR S). Data center growth will remain robust in the coming quarters, fueling demand for memory devices. In addition, cloud computing will continue to spur strong CPU, GPU, networking, ASIC, and DRAM and NAND demand through 2019, driving a consensus 3.63 percent year-to-year growth to reach the semiconductor revenue of $491 billion in 2019. Fab equipment spending (new and used) for 2018 is expected to increase by 14 percent to a record high of $63 billion, according to the last data from the SEMI World Fab Forecast, published by SEMI IR S. For 2019, fab equipment spending (new and used) is expected to increase 8 percent to another record of just under $68 billion. Memory continues to be the biggest swing factor in fab spending in 2018 and is expected to lead growth into 2020. 3D NAND will see the most capacity added in 2018 and 2019 with growth of 41 percent in 2018 and 27 percent in 2019, according to the SEMI World Fab Forecast. DRAM investment will see even stronger growth in 2018 and 2019 driven by new capacity addition as well as the continued technology shrink towards 1y/1z nm. For the first half of 2018, global spending for semiconductor fab equipment continues its growth momentum from 2017. Though we expect some softness in the second half of 2018, the outlook for 2019 remains robust with a fourth consecutive year of growth – the first such run since the 1990s. This prolonged growth cycle has been propelled by memory and will be extended by significant investment in China in 2019. Although a potential slowdown in 2020 is a concern, the overall outlook for semiconductor demand remains solid due to broad-based growth trends in data center, artificial intelligence (AI)/machine learning (ML), automotive, and industrial segments. Following are other SEMI forecasts for fab spending. Installed Capacity 3D NAND will see the most capacity added in both 2018 and 2019 with growth of 41 percent in 2018 and 27 percent in 2019. Foundry capacity growth is steady at 3 percent in 2018 and 6 percent in 2019, driven by both leading-edge and trailing-edge capacity buildup. 200mm fab capacity will increase 4 percent in 2018 and 3 percent in 2019, fueled by demand for MCU, sensors, PMIC, MOSFET and Driver IC. New Facilities / Construction Spending In 2018, there are 72 construction projects with investments totaling $15 billion, a year-over-year increase of 23 percent. Construction spending will reach all-time highs with China continuing its lead at US$7 billion in 2018, shattering its own record of $6.3 billion investment in 2017. Most construction spending in 2018 will be for Memory (just under $9 billion), primarily for 3D NAND followed by DRAM. Foundry will log second place in construction spending at just under $5 billion. Fab Equipment Spending Fab equipment spending (new and used) for 2018 is expected to jump 14 percent to a record high of US$63 billion, flat from the forecast issued in June 2018. Equipment spending (new and used) for 2019 is expected to increase 8 percent to another record of just under US$68 billion, a downward adjustment from +9 percent published in June 2018. We believe equipment spending will remain healthy, driven by solid, broad-based demand and predictable technology investments on top of constructive SEMICAP equipment fundamentals.
