Abstract

Stress relief layers are each provided on each circuit on an insulating substrate in a semiconductor module; a metal base coming into contact with the semiconductor module is divided into a thinned and low stiffened first metal base and a thickened and high stiffened second metal base; and the semiconductor module is bonded to the first metal base and then the first and the second metal bases are bonded to be integrated.
