ROHM has recently held an opening ceremony announcing the completion of a new building at ROHM Apollo's Chikugo plant started in February 2019 to enhance the production capacity of SiC power devices.
The new building is a state-of-the-art environmentally friendly factory that introduces a number of energy-saving technologies to its production facilities, with 100% of its electricity coming from renewable energy sources.
In addition, ROHM strengthened the BCM (Business Continuity Management) system by introducing various disaster countermeasures. And from January 2021, ROHM will begin to install production equipment and build a manufacturing system that can meet the medium- to long-term increases in demand for SiC power devices.
In addition to this new building, SiCrystal GmbH, a ROHM Group company that manufactures SiC wafers, is scheduled to start operating with 100% renewable energy from the next fiscal year, reducing CO2 emissions from purchased power at the plant to zero. As a result, all major production processes for SiC wafers will use environmentally friendly renewable energy.
The new building is designed to save energy by introducing measures such as a high-efficiency air conditioning system that makes effective use of exhaust heat, a pure water production system, and LED lighting, reducing CO2 emissions by 20% (approx. 7,000 tons) over conventional facilities.
