Automotive is driving SiC adoption

Press Release by System Plus Consulting & Yole Développement, July 2018

The SiC(1) power market is now on the road, asserts Yole Développement (Yole). Therefore, since 2017, the market research and strategy consulting company identified more than 20 strategic announcements, showing the dynamism of this market and attractiveness of the technology. Rohm, Bombardier, Cree, SDK, STMicroelectronics, Infineon Technologies, Littelfuse, Ascatron and more are part of the powerful ecosystem, presenting innovative products and revealing key partnerships and/or M&A(2) .
Today, SiC transistors are clearly being adopted, penetrating smoothly into different applications. Yole’s analysts forecast a US$1.4 billion SiC power semiconductor market by 2023. According to the Power & Wireless team at Yole, this market is showing a 29% CAGR(3) between 2017 and 2023.

Power SiC report, 2018 edition presents Yole’s deep understanding of SiC penetration in different applications including xEV, xEV charging infrastructure, PFC/power supply, PV, UPS, motor drives, wind and rail. In addition, it highlights the state-of-the-art SiC-based devices, modules, and power stacks. Yole’s analysts also describe the SiC power industrial landscape from materials to systems, and analyze of SiC power market dynamics. This report proposes a detailed quantification of the SiC power device market until 2023, in value and volume.
SiC adoption is accelerating: is the supply chain ready? Yole’s analysts reveal today their vision of the SiC industry.

SiC market is still being driven by diodes used in PFC(4) and PV(5) applications. However Yole expects that in five years from now the main SiC device market driver will be transistors, with an impressive 50% CAGR for 2017-2023. This adoption is partially thanks to the improvement of the transistor performance and reliability compared to the first generation of products, which gives confidence to customers for implementation.

Another key trend revealed by Yole’s analysts is the SiC adoption by automotive players, over the next 5-10 years. “Its implementation rate differs depending on where SiC is being used,” comments Dr. Hong Lin, Technology and Market Analyst, Compound Semiconductors at Yole. “That could be in the main inverter, in OBC(6) or in the DC/DC converter. By 2018, more than 20 automotive companies are already using SiC SBDs(7) or SiC MOSFET(8) transistors for OBC, which will lead to 44% CAGR through to 2023.”
Yole expects SiC adoption in the main inverter by some pioneers, with an inspiring 108% market CAGR for 2017-2023. This will be possible because nearly all carmakers have projects to implement SiC in the main inverter in coming years. In particular, Chinese automotive players are strongly considering the adoption of SiC.

The recent SiC module developed by STMicroelectronics for Tesla and its Model 3 is a good example of this early adoption. The SiC-based inverter, analyzed by System Plus Consulting, Yole’s sister company is composed of 24 1-in-1 power modules. Each module contains two SiC MOSFETs with an innovative die attach solution and connected directly on the terminals with copper clips and thermally dissipated by copper baseplates. The thermal dissipation of the modules is performed thanks to a specifically designed pin-fin heatsink.

“SiC MOSFET is manufactured with the latest STMicroelectronics technology design,” explains Dr. Elena Barbarini, Head of Department Devices at System Plus Consulting. “This technical choice allows reduction of conduction losses and switching losses”. STMicroelectronics is strongly involved in the development of SiC-based modules for the automotive industry. During its recent Capital Markets Day, the leading player details its activities in this field (Source: Automotive & Discrete Group presentation – May 2018). STMicroelectronics is also committed in the development of innovative packaging solutions. . System Plus Consulting proposes today a complete teardown analysis including a detailed estimation of the production cost of the module and its package.

PV has also caught the attention of Yole’s analysts during recent months. China claimed almost the half of the world’s installations in the last year. However due to new governmental regulations, Yole sees a PV market slowdown in short term and has lowered its expectation of SiC penetration for the segment. In general, system manufacturers are interested in implementing cost effective systems which are reliable, without any technology choice, either silicon or SiC.

“Today, even if it’s certified that SiC performs better than silicon, system manufacturers still get questions about long term reliability and the total cost of the SiC inverter”, comments Ana Villamor, Technology & Market Analyst, Power Electronics & Compound Semiconductors at Yole.
