A fire broke out at the 12-inch wafer production line of Renesas’s Naka Factory on March 19 due to an overcurrent in the plating equipment. Renesas said that the fire burned about 5% of the total area of the first floor. The Naka fab mainly manufactures MCUs and SoCs for automotive, industrial, and IoT-related applications. While Renesas officially aims to get the fab back to full operation within one month, TrendForce expects the immediate task of restoring the cleanroom and installing new equipment systems to take much longer than that. The repair of the production line will have to proceed meticulously so as to avoid the risks of manufacturing-related problems in the mass production of automotive chips later on. Three months is TrendForce’s conservative estimate for the fab to regain its former level of wafer-start capacity, meaning the tight supply of automotive MCUs will be further exacerbated going forward.

The Naka incident is not expected to result in additional orders for other foundries, given the current tight wafer-start capacity across the foundry industry

TrendForce indicates that the 12-inch Naka fab’s process technologies likely range from the 90nm node to the 40nm node. With regards to Renesas’s production lines for automotive chips, TrendForce expects the fire to impair the fab’s wafer-start capacities for products including automotive PMICs, certain V850 automotive MCUs, and first-generation R-Car SoCs. Other foundries, in particular TSMC, are able to support some of Renesas’s production, since 2/3 of their technologies are interoperable. However, it is exceedingly difficult for other foundries to allocate spare wafer-start capacities to make up for Renesas’s shortfall due to the existing wafer-start capacity crunch across the foundry industry.

Ranked third among automotive semiconductor suppliers in 2020, Renesas is also currently one of the top five largest automotive MCU suppliers at the moment. Other automotive MCU suppliers include STMicroelectronics, Infineon, NXP, TI, and Microchip. Although most of STMicroelectronics’ automotive MCUs are manufactured in-house, TrendForce believes that the Naka fire will not result in additional orders for Renesas’s competitors, including STMicroelectronics, since automotive semiconductors are currently in extreme shortage.

With Samsung, YMTC, SK Hynix, and Intel leading the charge, NAND Flash suppliers will maintain an aggressive effort to expand their production capacities throughout 2Q21, during which NAND Flash bit output will likely increase by nearly 10% QoQ, according to TrendForce’s latest investigations. On the other hand, orders from PC OEMs and Chinese smartphone brands since 1Q21, as well as recovering procurement activities from clients in the data center segment during 2Q21, will generate upward momentum propelling NAND Flash bit demand. Furthermore, buyers are actively stocking up on finished products, such as SSDs and eMMC, due to persistently limited NAND Flash controller supply. TrendForce therefore expects NAND Flash contract prices to increase by an average of 3-8% QoQ in 2Q21 after experiencing a 5-10% decline QoQ in 1Q21. In particular, as Samsung’s Line S2 fab in Austin has yet to resume full operation after the Texas winter storm, the supply of NAND Flash controllers going forward may be at risk, and Samsung’s ability to manufacture client SSDs will be further constrained as a result. In light of these factors, TrendForce is not ruling out the possibility that NAND Flash contract prices may increase by even more than current forecasts.

Contract prices of both client SSDs and enterprise SSDs are projected to rise due to delayed resumption at Samsung’s Line S2 fab

With regards to client SSDs, the persistent stay-at-home economy generated by the COVID-19 pandemic will likely result in strong demand for notebook computers in 2H21, while PC OEMs have raised their client SSD inventories as they manufacture more notebooks to meet demand. Given the high volumes of client SSD orders from PC OEMs, inventory level of NAND Flash suppliers is therefore likely to remain healthy. However, the shortage of NAND Flash controllers has yet to be resolved. Suspended operations at the Line S2 fab disrupted Samsung’s production of NAND Flash controllers, meaning some client SSD orders will not be fulfilled in 2Q21. Hence, the tight supply of finished products (i.e., client SSDs) will be further exacerbated. As such, client SSD contract prices are projected to increase by 3-8% in 2Q21.

With regards to enterprise SSDs, demand is expected to rebound from rock bottom in 2Q21, primarily because clients in the data center segment will ramp up their procurement activities after undergoing a period of inventory adjustment. In addition, demand for IT equipment from the governmental, healthcare, and financial services sectors will also gradually emerge. Other factors contributing to enterprise SSD demand include bids from Chinese telecom operators and increased IT equipment purchases from small and medium businesses globally. On the other hand, NAND Flash suppliers are no longer under pressure to destock via low prices, since their inventory levels have improved thanks to high demand from notebook manufacturers and smartphone brands. As the overall demand for NAND Flash rises, enterprise SSD contract prices are in turn expected to stabilize and experience a 0-5% growth QoQ in 2Q21.

High demand for Chromebooks will provide upward momentum for eMMC quotes, while contract prices of UFS are projected to undergo the lowest growths among NAND Flash products

eMMC contract prices will likely remain, for the most part, higher than expected despite the cyclical downturn in 1H21. In particular, strong demand from Chromebook manufacturers will provide upward momentum for eMMC quotes. Likewise, under the influence of NAND Flash controller shortage, eMMC buyers such as consumer electronics manufacturers will expand their procurement activities in order to build up their inventories. As a result, the overall eMMC demand will gradually ramp up in 2Q21. Conversely, the supply of eMMC controllers is still in shortage due to the fully loaded capacities across the foundry industry. Also, eMMC products under 32GB exclusively feature 2D NAND or 64L 3D NAND. Because production capacities allocated for these types of NAND Flash memories have been either reassigned to other 3D NAND products or scaled down, the oversupply of eMMC has been alleviated, and the long-term price drop of eMMC has subsequently come to a halt. In the short term, the shortage of controller ICs will result in a shortage of finished eMMC products. eMMC contract prices are therefore projected to increase by 3-8% QoQ in 2Q21.

Demand for UFS, which is primarily used for smartphones, is expected to remain high through 2Q21 because OPPO, Vivo, and Xiaomi have been aggressively procuring UFS since 4Q20, and Huawei spun off its Honor smartphone business unit. Buyers have also been anticipating an upcoming shortage of controller ICs and NAND Flash memory, leading them to build up their UFS inventories and therefore further driving up the overall UFS demand. On the supply side, inventory levels of suppliers have dropped significantly due to smartphone brands’ large-scale procurement activities previously. Although Chinese smartphone brands have yet to ramp up their bit demand, their existing level of demand still remains strong. Furthermore, clients from the data center segment are expected to increase their SSD procurement in 2Q21, and suppliers will maintain an aggressive approach regarding quotes in response. Even so, because smartphones account for the highest bit consumption share among all NAND Flash applications, NAND Flash suppliers are unlikely to significantly adjust their UFS quotes. As such, UFS contract prices are expected to increase by 0-5% QoQ in 2Q21, which is relatively lower compared to other NAND Flash products.

NAND Flash wafer contract prices are projected to increase by 5-10% QoQ as NAND Flash suppliers lower their bit shipment to the wafer market due to its lower profit margins

With regards to the NAND Flash wafer market, TrendForce has yet to observe an obvious improvement in the retail sales of end products such as SSDs, memory cards, and USB flash drives. However, as NAND Flash suppliers have been unable to make their scheduled delivery dates to OEMs due to an insufficient supply of controller ICs, module makers may stand to benefit from this and obtain more orders from OEMs, subsequently driving up the demand for NAND Flash wafers within the next one to two quarters, but the actual procurement of NAND Flash wafers will depend on whether the tight supply situation of controller ICs can be alleviated. On the other hand, inventories of NAND Flash suppliers have now fallen to mostly healthy levels thanks to procurement activities from smartphone brands since 4Q20. Suppliers have accordingly lowered their bit shipments to the NAND Flash wafer market (which yields a relatively lower profit margin compared to other product categories), due to the rising demand from notebook manufacturers and the expected recovery of the data center segment in 2Q21. On the whole, given the bullish market of mainstream products, such as smartphones and notebooks, TrendForce expects NAND Flash wafer contract prices to once again increase by 5-10% QoQ in 2Q21.

The third-generation semiconductor industry was impaired by the US-China trade war and the COVID-19 pandemic successively from 2018 to 2020, according to TrendForce’s latest investigations. During this period, the semiconductor industry on the whole saw limited upward momentum, in turn leading to muted growth for the 3rd gen semiconductor segment as well. However, this segment is likely to enter a rapid upturn owing to high demand from automotive, industrial, and telecom applications. In particular, the GaN power device market will undergo the fastest growth, with a $61 million revenue, a 90.6% YoY increase, projected for 2021.

TrendForce expects three factors to drive the rapid growth of the GaN and SiC markets in 2021: First, widespread vaccinations are projected to drastically curb the spread of the pandemic, thereby galvanizing a stable increase in the demand for base station components, as well as for components used in industrial energy transition, such as power inverters and converters. Secondly, as Tesla began adopting SiC MOSFET designs for its in-house inverters used in Model 3 vehicles, the automotive industry has started to place increasing importance on 3rd gen semiconductors. Finally, China will invest enormous capital into its 14th five-year plan starting this year and expand its 3rd gen semiconductor production capacity to ultimately achieve semiconductor independence.

Resurging demand from EV, industrial, and telecom sectors will bring about a corresponding increase in 3rd gen semiconductor device revenue

Although certain foundries, such as TSMC and VIS, have been attempting to manufacture GaN devices with 8-inch wafers, 6-inch wafers are still the mainstream. As the pandemic shows signs of a slowdown, the demand for RF front end in 5G base stations, for smartphone chargers, and for automotive on-board chargers has now gradually risen. As such, total yearly revenue from GaN RF devices is projected to reach US$680 million, a 30.8% increase YoY, in 2021, whereas GaN power device revenue is projected to reach $61 million, which is a 90.6% increase YoY.

In particular, the remarkable increase in GaN power device revenue can primarily be attributed to the release of fast chargers from smartphone brands, such as Xiaomi, OPPO, and Vivo, starting in 2018. These chargers enjoyed excellent market reception thanks to their effective heat dissipation and small footprint. Some notebook computer manufacturers are currently looking to adopt fast charging technology for their notebook chargers as well. Going forward, TrendForce expects more smartphone and notebook chargers to feature GaN power devices, leading to a peak YoY increase in GaN power device revenue in 2022, after which there will be a noticeable slowdown in its upward trajectory as GaN power devices become widely adopted by charger manufacturers.

On the other hand, 6-inch wafer capacities for SiC devices have been in relative shortage, since SiC substrates are widely used in RF front end and power devices. TrendForce expects yearly SiC power device revenue to reach $680 million, a 32% increase YoY, in 2021. Major substrate suppliers, including Cree, II-VI, and STMicroelectronics, are planning to manufacture 8-inch SiC substrates, but the short supply of SiC substrates will unlikely be resolved until 2022.
