摘要:
In a SiC-MOSFET power device for which a SiC substrate is used, a laminated insulating film having a charge-trapping characteristic is employed as a gate insulating film of the SiC-DiMOSFET, and charges are injected into the laminated insulating film, thereby suppressing a change in the gate threshold voltage.
