Fuji Electric will increase its production capacity of next-generation power semiconductors by approximately 10 times in FY2024 compared to FY2020. By 2025, the company aims to increase the sales of silicon carbide power semiconductors to about 10% of its semiconductor business, with the goal of capturing 2% of the global silicon carbide power semiconductor market by 2026. The use of silicon carbide (SiC) materials is expected to increase demand for next-generation power semiconductors with high energy efficiency, including electric vehicles (EVs). Currently, the company mainly produces products for Shinkansen parts and other products, and will establish a mass production system at its plants in Japan in order to prepare for the supply of products to the automotive industry.
Silicon carbide is known as an "ideal device" due to its stable chemical properties, high thermal conductivity, small thermal expansion coefficient, good wear resistance, high hardness and other characteristics, and is the most widely used in the current wide bandgap semiconductor. As the hottest market at present, new energy vehicles are also the field where silicon carbide can exert its most strength. As a result, it contributes to the extension of the range of pure electric vehicles and the miniaturization of batteries. The Matsumoto Plant (located in Matsumoto City, Nagano Prefecture), which has already started production of next-generation power semiconductors, will gradually increase production from FY2022.
According to relevant information, Fuji Electric is a Japan manufacturer of heavy electrical equipment, and its core technologies are power semiconductors and power electronics. Silicon carbide power semiconductors are its main focus of R&D and production in the near future, and Fuji Electric proposed as early as April 2021 that it would invest 120 billion yen (about 5.9 billion yuan) in power semiconductors in the next four years to increase production. In January 2022, it announced again that it would increase the investment to 190 billion yen (about 9.4 billion yuan), an increase of 60% from the original plan.
Fuji Electric's expansion plan is to establish a mass production system at its plants in Japan. It is reported that its Matsumoto plant in Matsumoto City, Nagano Prefecture, will increase production from 2022. Fuji Electric's subsidiary, Tsugaru Semiconductor, will also introduce a production line for silicon carbide power semiconductors at its plant, and mass production will begin in 2024.
