Abstract:
1. A semiconductor unit, comprising: a cooler having a fluid flow space; an insulating substrate bonded to the cooler through a metal; a semiconductor device soldered to the insulating substrate; an intermediate member interposed between the insulating substrate and the fluid flow space and having a first surface where the insulating substrate is mounted; and a mold resin having a lower coefficient of linear expansion than the intermediate member, wherein the insulating substrate, the semiconductor device and the cooler are molded by the mold resin, and a base of the cooler extending outward from the mold resin, wherein the intermediate member has a second surface that extends upward or downward relative to the first surface, the first surface is covered by the mold resin, and the second surface is covered by a resin cover.
