ROHM to build SiC power device manufacturing plant
Completion of a building using 100% renewable energy
German wafer factories to introduce eco-friendly processes by 2022


ROHM announced on the 7th that it had begun construction of a new building at the ROHM Apollo Chikugo Plant in Fukuoka, Japan, starting in February 2019 to strengthen the production capacity of SiC power devices, and that it would be completed in December 2020.

The new building features production facilities utilizing various energy-saving technologies and is an environmentally friendly plant, powered 100% by renewable energy. Various disaster countermeasures have also been implemented, strengthening the Business Continuity Management (BCM) system.

Manufacturing facility installation will proceed sequentially starting in January 2021, and plans are in place to establish a production system capable of responding to the mid- to long-term increase in demand for SiC power devices.

ROHM began mass production of SiC power devices in 2010, and is building a consistent production system to increase wafer size and improve production efficiency with the latest equipment.

Additionally, measures are being implemented to reduce environmental pollution during manufacturing. In addition to this new building, the German plant of SiCrystal, a group company that manufactures SiC wafers, is also scheduled to operate on 100% renewable energy from 2022.

ROHM stated, “Our main production process for SiC power devices will now be an environmentally friendly production system,” and “We will continue to contribute to improving device performance and protecting the environment.”
