The output value of the world’s top 10 foundries in 4Q21 reached US$29.55 billion, or 8.3% growth QoQ, according to TrendForce’s research. This is due to the interaction of two major factors. One is limited growth in overall production capacity. At present, the shortage of certain components for TVs and laptops has eased but there are other peripheral materials derived from mature process such as PMIC, Wi-Fi, and MCU that are still in short supply, precipitating continued fully loaded foundry capacity. Second is rising average selling price (ASP). In the fourth quarter, more expensive wafers were produced in succession led by TSMC and foundries continued to adjust their product mix to increase ASP. In terms of changes in this quarter’s top 10 ranking, Nexchip overtook incumbent DB Hitek to clinch 10th place.

TrendForce believes that the output value of the world’s top ten foundries will maintain a growth trend in 1Q22 but appreciation in ASP will still be the primary driver of said growth. However, since there are fewer first quarter working days in the Greater China Area due to the Lunar New Year holiday and this is the time when some foundries schedule an annual maintenance period, 1Q22 growth rate will be down slightly compared to 4Q21.

Top 5 foundries account for nearly 90% of global market share, Samsung recovers share with advanced processes

Looking at the top five industry players, TSMC’s 4Q21 revenue reached US$15.75 billion, a QoQ increase of 5.8%. Although 5nm revenue spiked thanks to the new iPhone, 7/6nm revenue dropped due to a weak Chinese smartphone market, becoming the only TSMC node in decline in 4Q21, and inducing a contraction in TSMC revenue growth in 4Q21, though TSMC still accounts for more than 50% of global market share. As one of TSMC’s few competitors in advanced processes below 7nm, Samsung strengthened 4Q21 revenue to US$5.54 billion, a quarterly increase of 15.3% owing to the gradual completion of new advanced 5/4nm process capacity and the mass production of new flagship products from major client Qualcomm. Although Samsung’s foundry business has posted record revenue, the slower ramp-up of advanced process capacity continues to erode overall profitability. Therefore, TrendForce believes that improving advanced process capacity and yield in 1Q22 is one of Samsung’s top priorities.

Constrained by limited growth in new production capacity and the fact that the new wave of wafers contracted at the latest pricing has yet to be produced, UMC’s revenue stalled slightly in 4Q21, to US$2.12 billion, up 5.8% QoQ. GlobalFoundries benefited from the release of new production capacity, product mix optimization, and new long-term agreement (LTA) pricing, pushing up ASP performance. Revenue in 4Q22 hit US$1.85 billion, up 8.6% QoQ. SMIC posted 4Q21 revenue of US$1.58 billion, 11.6% QoQ, due to mounting demand for products such as HV, MCU, Ultra Low Power Logic, and Specialty Memory as well as factors such as product mix adjustment and appreciating ASP.

Surpassing DB Hitek, Nexchip officially breaks into the top 10 in 4Q21

The foundries ranked 6th to 9th are HuaHong Group, PSMC, Vanguard International Semiconductor (VIS), and Tower Semiconductor (Tower), respectively. Each has benefiting from factors such as a utilization rate uniformly at full capacity, release of new production capacity, and adjustment of ASP and product mix, sustaining the growth of revenue performance. It is worth mentioning, the acquisition of Tower by Intel netted Intel mature process technologies and a customer base and expanded the diversity and production capacity of its foundry business. However, before this transaction is officially completed, Tower is still considered an independent entity in terms of the accounting process. TrendForce states, after Intel’s foundry business is properly integrated with Tower, Intel will officially enter the ranking of top ten foundries.

Coming in 10th on the top 10 foundry ranking is Nexchip with revenue of US$352 million and a quarterly growth rate of 44.2%, the fastest growth rate among the top ten, and officially surpassed DB Hitek. According to TrendForce investigations, the primary reason Nexchip was able to break into the top 10 in 4Q21 was the company’s diligent production expansion. Nexchip also plans to develop more advanced processes such as the 55/40/28nm nodes and multiple product lines including TDDI, CIS, and MCU, to compensate for its current single product line and limited customer base. Since Nexchip is currently ramping-up operations quickly, its growth performance in 2022 should not be underestimated.

Intel and AMD will be releasing new CPUs that support DDR5 DRAM solutions for PCs and servers this year. In response, the DRAM industry led by South Korean suppliers is developing solutions to complement the arrival of the new CPUs. In the midst of the gradual shift to DDR5, DRAM suppliers will also scale back the supply of DDR3 solutions, according to TrendForce’s latest investigations. With Korean suppliers accelerating their withdrawal from DDR3 production, Taiwanese suppliers yet to kick off mass production using newly installed capacities, and Chinese suppliers falling short of their expected yield rate, the global supply of DDR3 solutions will undergo an impending decline. With respect to the demand side, however, not only has the supply of networking chips been ramping up, but material shortage issues are also gradually easing. As such, buyers are now procuring DDR3 solutions ahead of time, resulting in a tight supply and demand situation in the DDR3 market. TrendForce therefore expects DDR3 DRAM prices to recover from a bearish first quarter and undergo a 0-5% QoQ increase in 2Q22.

On the supply side, Samsung and SK hynix have begun scaling back their DDR3 production while also planning to declare EOL (end of life) for their DDR3 offerings, such as 1/2Gb and 4Gb chips. It should be noted, however, that Micron’s DDR3 solutions will not reach EOL even by 2026, meaning the company will still offer DDR3 solutions long after its two Korean competitors have stopped doing so, according to TrendForce’s understanding. Also worth noting is that Micron is migrating its DDR3 production to a US-based fab that mainly manufactures specialty DRAM solutions. Nevertheless, since this fab’s production capacity will be divided between products for consumer and automotive applications, TrendForce believes that the aforementioned migration will tighten Micron’s supply of consumer DRAM solutions because the US fab will give priority to automotive DRAM solutions that offer a higher gross margin and are currently enjoying surging demand.

Although Taiwan-based DRAM suppliers that focus on promoting DDR3 solutions, namely, Nanya Tech and Winbond, are in the process of capacity expansion, their new production lines will not be operational until 2023-2024. Hence, the contribution from the newly added capacities is not expected to drive up DDR3 supply substantially this year. Chinese suppliers, including CXMT and GigaDevice, are continuing to collaborate in DDR3 development, though their capacity increases and yield rate improvements have both fallen short of market expectations. After being added to the Entity List, JHICC, yet another China-based DRAM supplier, is now dealing with severe restrictions with respect to procuring equipment, making it difficult for JHICC to raise its wafer input. Furthermore, the company has no spare resources that can be allocated to R&D and pilot runs. As a result, JHICC still primarily manufactures DDR4 4Gb chips at its initial 25nm node, with no DDR3 production at the moment.

With regards to demand, DDR3 consumer DRAM is primarily used in end-devices such as STBs and networking products (e.g., GPON, routers, and modems), which do not require high-performance SoCs. While the foundry industry suffered a severe shortage of wafer capacities allocated to logic ICs in 4Q21, production capacities for relatively low-margin chips were noticeably impacted in turn. Along with a preexisting component mismatch situation, most manufacturers found themselves unable to assemble end-devices. Moving into early 2022, however, the supply of certain materials, including those used in foundry operations, saw a gradual improvement. As various components needed for device manufacturing became available after Lunar New Year, certain buyers have once again kicked off their consumer DRAM procurement activities.

In addition, DRAM spot prices shifted from a prior decline to a strong upturn at the end of last year as the Chinese government ordered a month-long lockdown in Xi’an. The ensuing price hike, which has lasted for two months, subsequently led buyers to procure even more DRAM ahead of time in anticipation of further price hikes. Hence, although the demand for end-products has yet to make a full recovery, buyers are now slowly and steadily procuring consumer DRAM in order to avoid either higher upcoming prices or even an inability to secure consumer DRAM inventory.

Global smartphone production came to 356 million units for 2021, showing a QoQ increase of 9.5%, according to TrendForce’s latest investigations. The second half of last year saw demand injections related to the peak promotion season for e-commerce platforms and year-end holiday sales. These factors thus bolstered smartphone production and resulted in 4Q21 seeing the highest QoQ growth rate for the year. Apple’s new iPhones were the primary growth driver. On the other hand, the performances of a few smartphone brands were constrained by the shortage of some key components. Hence, the total smartphone production for 4Q21 was slightly lower compared with 4Q20 or even 4Q19.

Apple took production leadership in 4Q21 with record high of 85.5 million units

After unveiling the iPhone 13 series in September, Apple started aggressively ramping up the shipments of these new devices to meet market demand. Owing to its fast-paced sales and marketing rhythms, Apple has been able to take first place in the quarterly ranking of smartphone brands by production market hare for many fourth quarters, and 4Q21 was no exception. Besides maintaining its top position in the fourth-quarter brand ranking, Apple raised its quarterly iPhone production to a new record high of 85.5 million units, a 66.0% QoQ increase. In the aspect of pricing strategy, the prices of the new iPhone 13 models were reasonable for consumers, while the price reductions for the older iPhone models were noticeable as well. Moreover, the capturing of the market share left by Huawei can be considered as the main factor behind Apple’s stellar performance in 4Q21. Over time, the orders for Huawei’s flagship models (i.e., the P and Mate series) have been gradually replaced by iPhone orders. In terms of annual production, Apple reached 233 million units for 2021, up from almost 200 million units for 2020. The growth was mainly attributed to an expansion of Apple’s market share in China from 10% to 16%. Samsung took second place in the global brand ranking for 4Q21 with 71 million units, a 2.9% QoQ increase. In 2Q21, the spread of COVID-19 outbreaks in Vietnam affected smartphone production facilities in the country and lowered Samsung’s capacity utilization rate. But apart from that quarter, Samsung’s performance remained stable for the other three quarters of last year. For the ranking of smartphone brands by annual production, Samsung was still the leader for 2021 with 275 million units.

OPPO (including Realme and OnePlus) took third place in the ranking with a quarterly production of 48 million units, a 5.9% QoQ decrease, for 4Q21. Xiaomi (including Redmi, POCO, and Black Shark) took fourth place with a production of 45.5 million units, a 2.2% QoQ increase. Fifth-ranked Vivo (including iQoo), on the other hand, reduced its smartphone production by 11.8% QoQ to 30 million units. As these three Chinese brands’ target markets and product strategies show significant overlap, their control of key components that are currently in shortage will have a direct impact on their production volumes going forward. It should also be pointed out that Honor, which was spun off from Huawei in early 2021 and underwent a period of corporate restructuring and component procurement in 1H21, experienced a meteoric rise in 2H21. Much like other Chinese brands, Honor adopts a sales strategy that primarily focuses on the Chinese market, meaning Honor’s smartphone business will continue to affect OPPO, Xiaomi, and Vivo, all of which place a top priority on domestic sales.

Annual smartphone production for 2022 will likely reach 1.381 billion units despite potential decline

Assuming that the global spread of the COVID-19 pandemic continues to slow, TrendForce expects annual smartphone production for 2022 to undergo a slight YoY increase of 3.6% to 1.381 billion units. Not only is smartphone demand expected to decline in China, which represents the largest consumer market in the world, but other markets will also exhibit only limited growth. Hence, the leading growth drivers will come from both cyclical replacement demand and new demand from emerging markets. Notably, in addition to factors such as foundry capacity allocation, global inflation, and energy shortage, whether an economic recovery will bring about positive change for the smartphone market will continue to influence the overall performance of the industry. TrendForce therefore believes that the annual smartphone production for 2022 may still face potential downside risks.

Regardless, the recent war between Russia and Ukraine has generated a host of issues including exchange rates, inflation, and logistics problems that affect smartphone sales in Eastern Europe. With regards to the market share of smartphone brands in Russia and Ukraine last year, the top three brands by sales included Samsung, Xiaomi, and Apple, with a combined 45 million units sold, accounting for 3% of the global total. Preliminary assessments indicate that the ongoing war will not have a drastic effect on smartphone production for 2022, though TrendForce also does not rule out the possibility that the resultant global economic problems may affect overall smartphone demand.

In 4Q21, NAND Flash bit shipments grew by only 3.3% QoQ, a significant decrease from the nearly 10% in 3Q21, according to TrendForce’s investigations. ASP fell by nearly 5% and the overall industry posted revenue of US$18.5 billion, a QoQ decrease of 2.1%. This was primarily due to a decline in the purchase demand of various products and a market shift to oversupply causing a drop in contract prices. In 4Q21, with the exception of enterprise SSD, the supply of which was limited by insufficient upstream components, the prices of other NAND Flash products such as eMMC, UFS, and client SSD, all fell.

TrendForce’s summary of NAND Flash market sales performance in 2021 is as follows: although there have been signs of weakening since 2H21, thanks to remote services and cloud demand driven by the pandemic, revenue performance still grew significantly compared to 2020. Revenue reached US$68.6 billion, up 21.1% YoY, the second-biggest increase since 2018.

NAND Flash revenue fell for most manufactures in 4Q21 due to PC OEM destocking

There were some changes to the top three NAND Flash revenue rankings in 4Q21 compared 3Q21, Samsung and Kioxia remained in the top two while third place was replaced by Western Digital (WDC). Although there was still demand coming from data centers, as PC OEMs continued to deplete client SSD inventories and demand from China’s smartphone market weakened, stocking momentum was affected by component mismatch issues, resulting in a decline of approximately 5% in Samsung Electronics’ bit shipments in 4Q21. After the market shifted to oversupply, ASP also fell by approximately 5%, leading to Samsung Electronics posting 4Q21 revenue of US$6.110 billion, a QoQ decrease of 6.1%.

Second ranked Kioxia continued seeing strong demand from data center clients in 4Q21 but this was offset by inventory adjustment and reduced purchasing on the part of PC OEMs. Bit shipments declined slightly by 1% and ASP remained flat even in the face of weakening market demand, which was better performance than that of other suppliers in the same period. Revenue in 4Q21 reached US$3.543 billion, a QoQ decrease of 2.6%.

WDC was another company that benefited from continued strong stocking demand from major US smartphone clients for new 5G flagship phones which offset the impact of weak client and enterprise SSD sales, for bit shipment growth of 13%. However, as the proportion of consumer goods grew, ASP declined by 6%. WDC’s NAND Flash division posted 4Q21 revenue of US$2.62 billion, a QoQ increase of 5.2%.

Benefiting from continued stocking from data center clients and US-based smartphone brands, SK hynix’s bit shipment growth remained above 10%, in line with original forecasts. However, ASP was affected by weaker mobile phone shipments in China and inventory adjustment at PC OEMs. Pricing fell by nearly 10% which offset overall growth momentum. Revenue posted by SK hynix’s NAND Flash division in 4Q21 increased by 2.8% to US$2.615 billion.

Micron was similarly affected by inventory adjustments undertaken on the part of PC OEMs and data center clients.  Although Micron’s 176-layer products continue to be adopted, shipments in 4Q21 were flat compared to 3Q21 and ASP fell approximately 5% as the growth rate of supply outpaced demand, leading to a decline of 4.7% in Micron’s 4Q21 NAND Flash revenue to US$1.878 billion.

Solidigm’s 4Q21 production capacity was still being affected by the impact of supply chains (such as PMIC supply) on enterprise SSD, resulting in a continued decline in bit shipments of nearly 5% in 4Q21. At the same time, while orders for laptops are still strong, Solidigm actively increased bits shipments of PC QLC SSDs in order to reduce production capacity, causing a drop in ASP and a 4Q21 NAND Flash revenue performance of only US$996 million, a 9.9% decline.

Looking forward to 1Q22, TrendForce states that with the advent of the demand off-season, demand for major applications will show a seasonal decline, exacerbating the phenomenon of oversupply and driving the contract price of products to fall further. Falling prices and shrinking volume is expected to further reduce the revenue level of the NAND Flash industry. Referencing information released by TrendForce on Feb. 10, it is worth noting that market expectant psychological factors in 2Q22 generated from the previous Kioxia and WDC raw material pollution incidents will change the supply and demand situation after February and certain products with additional orders and non-quarterly contract prices will immediately reflect a pricing increase. This will help reduce the decline in the output value of NAND Flash in 1Q22.

The pandemic has impeded the supply of many end-user devices such as smartphones, servers, PCs, and niche consumer electronics components, indirectly leading to a decline in a willingness on the procurement-end to stock relatively abundant memory chips, according to TrendForce research. This is most obvious in the stance of PC OEMs holding more than 10 weeks or more of DRAM inventory. Therefore, most DRAM fabs experienced a drop in shipments in the fourth quarter of 2021 and declining purchasing momentum has also led to a downward trend in DRAM price quotations. Total 4Q21 DRAM output value decreased by 5.8% QoQ, reaching US$25.03 billion, with only a few suppliers such as SK hynix bucking this trend.

Looking forward to 1Q22, although material shortages for some components can be alleviated, the first quarter is already an off season for demand and buyers’ inventories are still flush. Thus, the purchasing-side will largely concentrate on destocking, with overall purchasing momentum remaining sluggish. Thus, DRAM pricing in the first quarter of this year is expected to face greater pressure than in the fourth quarter of last year and overall DRAM output value may fall further.

4Q21 DRAM price drop causes downturn in manufacturer profit levels

In terms of revenue performance, price quotations from the three major DRAM manufacturers all declined with slightly differing shipments trends. Shipments from both Samsung and Micron fell due to poor end-user demand, with revenue down 9% and 8%, respectively. In terms of market share, Samsung dropped slightly to 42.3% while still ranking first, SK hynix climbed to nearly 30%, ranking second, and Micron dropped slightly to 22.3%.  Pricing gaps between these three DRAM manufacturers in 1Q22 is expected to be narrow, but since SK hynix had a relatively high base period of shipment in the 4Q21, the company expects a decline in its shipments slightly higher than the industry average which will reduce its 1Q22 market share slightly.

In terms of profit performance, the operating profit margins of Samsung, SK hynix, and Micron (September-November financial reporting) fell to 50%, 45%, and 41%, respectively, due to the cost optimization resulting from an increase in the proportion of advanced processes not being  enough to make up for the decline in price quotations. TrendForce believes that the downturn trend in profit margins is likely to intensify in 1Q22 and DRAM suppliers will face sharper profit decline. Manufacturers can only increase the proportion of advanced processes and optimize their product portfolio to reduce the impact brought on by price pressure.

Specialty DRAM market conditions also weak in 4Q21, with Taiwanese manufacturer revenue falling as well

As the demand for specialty DRAM end-user applications such as TVs and consumer electronics products dropped significantly in 4Q21, coupled with the impact of material shortages in the supply chain, client demand for DRAM shipments also cooled substantially. The 4Q21 specialty DRAM price decline was also comparable to that of mainstream products, in turn impacting the revenue performance of Taiwanese manufacturers focused mainly on the consumer market. From the perspective of Nanya Tech, the combination of falling volume and price reduced its revenue in 4Q21 by approximately 10%, while its operating profit rate fell to 37.5% due to the decline in price quotations. Winbond’s small-capacity (1/2Gb) market was also affected by components mismatch issues, but the impact was relatively small and its 4Q21 revenue fell slightly by close to 4%. PSMC’s (revenue calculation is primarily based on its self-produced standard DRAM products and does not include its DRAM foundry business) revenue fell slightly by approximately 1%. If its foundry revenue is added, then its revenue grew by 6%, reversing a downward trend. This demonstrates that locking-in long-term contracts early is a good strategy.

Faced with reversal in the DRAM market, it is TrendForce’s understanding that the solutions of the three major Taiwanese manufacturers are as follows: Nanya Tech can allocate 20nm production capacity to produce DDR3 (better gross profit) when DDR4 market conditions are poor and invest more resources in the research and development of new 1X nm processes.  If yield improves rapidly, this will provide some contribution before the completion of its new factory in 2024. In addition to continuing to focus on niche small-capacity products, Winbond is also strengthening research and development of 25 nm and next-generation 20 nm products, expected to be introduced directly when its Kaohsiung Lujhu factory starts mass production. As for PSMC, by locking clients into long-term contracts, it can plan 2022 production in advance and continue to maximize its greatest advantages. In accordance with market conditions and gross profit levels, it will allocate production capacity between logic IC and memory products.
