Abstract:
1. A method of manufacturing a semiconductor device, comprising: forming terminal portions convexly protruding on a surface of first conductive foil by etching the first conductive foil except portions to become terminals; superimposing a resin on the first conductive foil such that the terminal portions are embedded in a resin sheet; constructing a laminated sheet by superimposing second conductive foil on the resin sheet; forming a conductive pattern by etching the second conductive foil; electrically connecting the conductive pattern and the terminal portions; electrically isolating the terminal portions from each other; fixing a semiconductor element to the laminated sheet and electrically connecting the semiconductor element and the conductive pattern; and forming sealing resin on a surface of the laminated sheet such that the semiconductor element is covered by the sealing resin.
