At present, semiconductor technology is the main body of evolution that constitutes the intelligence of automobiles, and it is also the core key to promoting electrification. So it's interesting to track semiconductor market and technology changes around the world, and to observe the dynamics of major players and new entrants. In Europe, at present, from the perspective of revenue and business development, it is worth paying attention to Infineon, NXP and ST, and today I will sort out their performance and business development priorities in 2021.
Figure 1 At present, the world's major automotive semiconductor companies
(Note: The main reason for tracking is based on the revenue of the automotive semiconductor market in 2020 and the existing business, but sensors, MCUs, and power semiconductors are not all automotive semiconductors.) ）
Figure 2 Automotive semiconductor market and business segmentation in 2020
1) Infineon
Infineon's overall revenue for 2021 was EUR 11 billion, an increase of 29%, and its operating margin increased from 13.7% to 18.7% (a new high after 2008), of which the automotive business revenue was EUR 4.8 billion, an increase of 37.5%. About half of the automotive products are power semiconductors, mainly discrete components, IGBTs and MOSFETs; MCUs account for about 25%, sensors account for about 18%, and storage accounts for about 7%.
Figure 3 Infineon's automotive business
In terms of power electronics, Infineon is the world's largest supplier of automotive IGBT (market share of more than 50%), BYD is an Infineon customer, and if you consider wafer cutting and repackaging, Infineon has a market share of more than 60% in China. At present, in terms of SiC, Infineon's business is just starting out, and its customers are Xiaopeng and Hyundai, as well as several Japanese and American car companies. The SiC market size is forecast to be $1 billion in 2025, and the market share may reach 30%. In terms of investment, Infineon's main investment focuses on third-generation power semiconductors, and will invest more than 2 billion euros to expand the production capacity of SiC and GaN semiconductors, starting construction in June 2022. Infineon will build a third plant at its Kulim plant in Malaysia, with a new fab to be completed in the summer of 2024 and the first fabs rolling off the production line in the second half of 2024.
(Note: This piece seems to be somewhat optimistic about market share)
Figure 4 Automotive power semiconductors at Infineon
Infineon's top 10 customers in the automotive sector are: Bosch, Continental Motors, Hitachi, Denso, Aptiv, Keihin, Valeo, Mando, HELLA, BYD. From the current point of view, Infineon's MCU (TC3x) in the power and chassis field accounts for a larger proportion of advantages, mainly relying on the binding of the first few major customers.

2）NXP
In 2021, NXP's overall revenue was $11.1 billion, up 29.1% year-on-year, of which automotive revenue reached $5.5 billion, an increase of 44.7% year-on-year. With a focus on MCUs and perception, NXP began to seek innovation at the process level, introducing TSMC's 16nm FinFET process (previously the most advanced was the 28nm FD-SOI process). The first to use the 16-nanometer process were the S32G2 and S32R294. The S32R294 is a chip for 4D millimeter-wave radar, followed by the S32R45, which introduces the ARM Cortex-A53 core and the Cortex-M7 core.

3）ST
In 2021, ST revenue was $12.76 billion (up 24.9%) and operating margin increased from 14% to 19%. ST's automotive business accounts for 34% of total revenue, and the top ten customers are Apple, Bosch, Continental, HP, Huawei, Mobileye, Nintendo, Samsung, Seagate and Tesla.
Figure 7 Business composition of ST
From the perspective of the automotive business, ST is the exclusive supplier (foundry model) of Tesla SiC MOSFET, and the new part mainly includes the establishment of a strategic alliance between Hyundai Motor and Renault in SiC MOSFET to supply advanced power semiconductor chips. From the current point of view, ST has a market share of more than 60% in the in-vehicle SiC MOSFET market.

brief summary:
As more and more semiconductor companies enter the automotive business, especially many new forces are willing to add non-security and fun functions. In fact, the opportunities in the field of automotive semiconductors are much better than before, especially the expansion speed of traditional automotive semiconductor companies mainly focuses on power semiconductors and perception.
