High-performance SiC power devices and modules with high temperature operation

The expectation for SiC devices in advanced power electronics applications for saving energy has been still larger. The 4H-SiC planer MOSFETs with high blocking voltage (1300 V) and large current (40 A) were fabricated. In addition, we have succeeded in fabricating the larger current (300 A) 4H-SiC trench MOSFET with low-on resistance (2.6 mΩ cm
²
). And, regarding high-temperature operation, SiC IPMs can be successfully fabricated by using a new bonding soldering method which can withstand even 400°C.
