Rohm to start mass production of Full-SiC power module 1200V/100A
ROHM has recently announced the first mass production of SiC power modules (1200V/100A rated) comprised entirely of SiC power elements.
Rohm has announced mass production of SiC power modules (1200V/100A rated) comprised entirely of SiC power elements. Incorporating SiC inverters and converters for power conversion in industrial equipment provides a number of advantages over typical silicon-based IGBT modules:
These new modules are also expected to make major strides towards addressing global environmental issues, including greenhouse emissions and resource shortages.

SiC technology is expected to have a significant impact in the power electronics sector (e.g. industrial equipment, solar cells, electric cars, and trains) due to its superior material properties (i.e. smaller power conversion loss) compared with silicon (Si). Rohm has been working continuously for a number of years on developing SiC products and in 2010 was the first supplier in the world to successfully mass produce SiC SBDs and MOSFETs.

Development of "full SiC" modules for use in power devices, however, has been impossible up to now despite significant efforts by several semiconductor manufacturers due to unstable reliability at high temperatures. ROHM was able to overcome these problems by developing unique screening methods and defect suppression technology that guarantees reliability, as well as a control system that prevents characteristics deterioration at high temperatures (up to 1700°C), making it possible to establish the industry's first mass production system for SiC power modules.
