SiC power modules: Rohm creates a joint venture in China

Zhenghai Group and the Japanese Rohm signed an agreement to create a joint company in the power modules sector. The new company, called Haimosic, is expected to be created in China in December 2021 and will be 80% owned by Shanghai Zhenghai Semiconductor Technology, subsidiaries of the Zhenghai group, and 20% by Rohm.

Haimosic will be responsible for the design, manufacture and sale of power modules using silicon carbide (SiC) power devices for new energy vehicles. The agreement enables the development of power modules by combining inverter technology from Zhenghai group companies, module technology from both companies and SiC semiconductors from Rohm.

Mass production of Haimosic SiC modules for electric vehicles will start from 2022. Zhenghai Group and Rohm will work closely with this new company to help further technological innovation through development and use widespread use of SiC power modules.

« In more than 30 years of development, Zhenghai Group has accumulated rich industrialization experience in many industries such as rare earth permanent magnets, regenerative medicine, automotive interior and information technology. The Zhenghai group has decided to make the power modules activity a strategic activity for the group, providing it with the greatest support in terms of capital and human resources. By combining Rohm’s advanced power device technology with Zhenghai’s industrialization capabilities, we believe that the joint company will contribute to the development of China’s power module industry. “Said Bi Bohai, president of Zhenghai Group.
