Zhenghai Group and ROHM Agree to Establish a Joint Venture in SiC Power Module Business
Willich-Münchheide, Germany, October 25, 2021 – Zhenghai Group Co., Ltd. (Zhenghai Group) and ROHM Co., Ltd. (ROHM) have signed a joint venture agreement to establish a new company in the power module business. The new company, “HAIMOSIC (SHANGHAI) CO.,LTD.” is scheduled to be established in China in December 2021, and will be owned 80% by Shanghai Zhenghai Semiconductor Technology Co., Ltd. (Zhenghai Semiconductor) of Zhenghai Group and 20% by ROHM.

The new company will engage in the joint venture business of development, design, manufacturing and sales of power modules using silicon carbide (SiC) power devices, with the aim of developing a power module business that is ideal 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 cutting-edge SiC chips.

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 Zhenghai Group and ROHM will work closely with this new company to contribute to further technological innovation through the development and widespread use of SiC power modules.

Bi Bohai, Chairman of Zhenghai Group Co., Ltd.
ROHM is a respected global leader in SiC devices. 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. 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. The Zhenghai Group has determined to make the power module business a strategic business for the Group, giving it the greatest support in terms of capital and human resources. Combining ROHM's advanced power device technology with Zhenghai's industrialization capabilities, we believe that the joint venture will contribute to the development of China's power module industry.

Isao Matsumoto, President and CEO of ROHM Co., Ltd.
We are very pleased to establish a joint venture with the Zhenghai Group, which has a wide range of businesses in China. As a leading company in SiC power devices, ROHM has been developing the world's most advanced devices and providing power solutions together with peripheral components. 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.
