Patent ID: 8294253

Claim:
A semiconductor device comprising: an electronic component which includes an electrode pad forming face on which electrode pads are formed, and a back face opposite to the electrode pad forming face; a sealing resin which includes a first face provided on the electrode pad forming face side and a second face provided on the back face side, and which is provided around the electronic component to seal up side faces of the electrode component; a multilayer wiring structure which is provided on the first face of the sealing resin, and in which a plurality of insulating layers, a wiring pattern and external connecting pads are stacked on each other, the plurality of insulating layers including a first insulating layer being in contact with the sealing resin; and a conductive member which is provided in a through-hole passing through the sealing resin and the first insulating layer, wherein the wiring pattern is directly connected to the electrode pads and the external connecting pads, and includes a wiring provided on a first contact face of the first insulating layer opposite to a second contact face of the first insulating layer being in contact with the sealing resin, wherein the conductive member is connected to the wiring, wherein the conductive member has a height smaller than a value obtained by adding a thickness of the sealing resin to a thickness of the first insulating layer, and wherein the back face of the electronic component is exposed.
