Haimosic is a joint venture in China between Zhenghai and Rohm to make SiC power modules for electric vehicles

Rohm has teamed up with the Zhenghai Group in China to set up a joint venture for silicon carbide (SiC) power modules.

The new company, called Haimosic (Shanghai) is planned for December 2021 and will be 80 percent owned by Shanghai Zhenghai Semiconductor Technology and 20 percent by Rohm.

Haimosic will develop, design, manufacture and sell SiC power modules for traction inverters and other applications in new energy vehicles. The agreement enables to develop highly efficient power modules by combining the inverter technology of the Zhenghai Group companies, the module technology of both companies, and Rohm's SiC power devices. The module products to be developed through the new company are already scheduled to be used in electric vehicles, and mass production will begin from 2022.

“The establishment of a joint venture between Rohm and the Zhenghai Group to develop the SiC power module business will surely bring new changes to the power module market,” said Bi Bohai, Chairman of the Zhenghai Group. “Through more than 30 years of development, Zhenghai Group has accumulated rich industrialization experience in many industries such as rare earth permanent magnet, regenerative medicine, automobile interior, and electronic information.”

“We are very pleased to establish a joint venture with the Zhenghai Group, which has a wide range of businesses in China,” said Isao Matsumoto, President and CEO of Rohm. “The development of power modules in the new company will encourage the use of SiC power devices in new energy vehicles, which are gaining momentum in China, as well as play an important role in other application research. Through the business of the new company with Zhenghai Group, we will aim for the further development and evolution of both companies.”

Starting with shadow mask manufacturing in the early days of the company's founding, the Zhenghai Group has diversified into industries such as rare earth permanent magnets, regenerative medicine, automobile interiors, and electronic information with over 12 subsidiaries.
