Abstract:
A semiconductor device comprising:a resin member of a predetermined thickness, said resin member being made of a seal resin; a semiconductor element sealed inside said resin member, having a back surface exposed at a top surface of said resin member, and having an active surface facing downward; metal interconnections formed directly on the bottom surface of the resin member, said metal interconnections having a top surface, said top surface of said metal interconnections being entirely covered by said resin member such that said metal interconnections are formed in their entirety on said bottom surface of said resin member; connection terminals extending downward from the active surface of the semiconductor element and having bottom ends connected to top surfaces of said metal interconnections; a solder resist layer covering the entire bottom surface of said resin member including said metal interconnections; and connection bumps formed on the bottom surfaces of said metal interconnections, passing through said solder resist layer, and projecting downward.
