Power module and fabrication method for the same
A power module includes: an insulating layer; a first metallic plate disposed on the insulating layer; a first semiconductor chip disposed on the first metallic plate; a first adhesive insulating layer and a second adhesive insulating layer disposed on the first metallic plate; a first metallic land for main electrode wiring disposed on the first adhesive insulating layer; and a first metallic land for signal wiring disposed on the second adhesive insulating layer. There can be provided a power module having reduced cost, reduced warpage of the whole of a substrate, stabilized quality, and improved reliability; and a fabrication method for such a power module.
