DENSO Corporation and Fuji Electric Co., Ltd., announced that a
semiconductor supply plan submitted jointly by the companies has been approved by the Ministry of Economy,
Trade and Industry. Under this plan, the companies will take part in joint investment and production of silicon
carbide (SiC) power semiconductors to develop and strengthen frameworks for the supply of said semiconductors.
Power semiconductors are vital to the efficient supply of electric power. Demand for power
semiconductors has been rising rapidly given that they are used in electrified vehicles, which are being adopted
at an accelerated pace amid the push for the decarbonization of society. In comparison to prior silicon
semiconductors, SiC power semiconductors are able to deliver superior performance under high-temperature,
high-frequency, and high-voltage conditions. These devices are therefore anticipated to make large contributions
to reductions in power loses as well as to more compact and lighter-weight designs for battery electric vehicle
systems and other power electronics. Accordingly, growth in demand is projected for SiC power semiconductors.r>
In response to electrification trends, DENSO has advanced SiC technology development projects
targeting increased quality and efficiency in relation to everything from wafers and element devices to modules
and inverters. Meanwhile, Fuji Electric has constructed extensive frameworks encompassing all tasks
spanning from the development of SiC power semiconductor elements that enable increased efficiency and
more compact designs for power electronics equipment to mass production of the related modules. Based on the
approved plan, these companies will combine their respective automotive product development and production
technology capabilities in a joint effort to expand their capacity for the efficient and stable supply of SiC power
semiconductors throughout Japan.
Through this partnership, the companies will contribute to the development of semiconductor supply
frameworks within Japan and to the improvement of the international competitiveness of Japan’s domestic
semiconductor and automotive industries. In addition, this partnership is anticipated to help advance the
decarbonization of society.
