Reliable semiconductor device and method of manufacturing the same

The present invention provides a semiconductor device and a method of manufacturing the same improved in reliability of a gate insulating film by increasing a total charge amount Qbd by suppressing a film stress of a gate electrode formed of a polysilicon film, to a low value. Since the film stress...
