Abstract:
1. A power semiconductor device comprising: a power semiconductor element having a back surface bonded to a wiring pattern on an underlayer and a surface electrode on a surface opposing to said back surface; a cylindrical communication part having a bottom surface bonded on at least one of said surface electrode of said power semiconductor element and said wiring pattern; a transfer mold resin having a concave part which exposes an upper surface of said communication part and covering surfaces other than said upper surface of said communication part, said underlayer, said wiring pattern, and said power semiconductor element; and a plurality of external terminals, each having one end inserted in said upper surface of said communication part and an other end guided upward, wherein at least one of said external terminals has, between said one end and said other end, a bent area which is bent in an L shape, and said bent area is embedded in said concave part of said transfer mold resin.
