ABSTRACT:
A semiconductor device includes a stage having top and bottom surfaces, a semiconductor element which is mounted on the top surface of the stage, a package part which is made of a first resin and encapsulates the semiconductor element so that a surface of the package part and the bottom surface of the stage lie on substantially the same plane, and a radiation part which is made of a second resin and is provided directly on the bottom surface of the stage and the surface of the package part. The second resin includes a filler material selected from a group consisting of metal powders and insulator powders so that a thermal conduction of the second resin is greater than that of the first resin.
