Abstract:
1. A semiconductor device comprising: a base plate; a semiconductor constructing body which is formed on the base plate and has a semiconductor substrate and a plurality of external connection electrodes formed on the semiconductor substrate; an electrical insulating layer which is formed on the base plate around the semiconductor constructing body; an upper insulating film which covers the semiconductor constructing body and the electrical insulating layer; upper interconnections formed on the upper insulating film and connected to the external connection electrode of the semiconductor constructing body on the electrical insulating layer, each of the upper interconnections having a connection pad portion; and a heat dissipation layer which is formed on at least one of an upper surface of the upper insulating film and a lower surface of the base plate and connected to the semiconductor constructing body, wherein the heat dissipation layer is made of the same material as that of the upper interconnections, and wherein the heat dissipation layer is electrically insulated from the upper interconnection.
