Abstract:
1. A semiconductor device that includes a double-sided electrode package and a semiconductor chip having a plurality of electrodes, the semiconductor device comprising: a package substrate comprised of a core material that is an insulator and that is provided with a plurality of through electrodes each extending from a first surface to a second surface of the core material, the semiconductor chip being placed on said first surface of the package substrate; a plurality of electrode pads that are comprised of wires formed on said first surface of the package substrate in direct contact with respective through electrodes of the plurality of electrodes and that are electrically connected to respective ones of the plurality of electrodes of the semiconductor chip; a plurality of external electrode pads for external connection that are formed on said second surface of the package substrate in direct contact with respective through electrodes of the plurality of through electrodes and that are electrically connected to respective ones of the plurality of electrode pads via respective ones of the through electrodes, the plurality of external electrode pads and the package substrate extending in the same plane and forming a flat external surface; a sealing resin layer having a ground surface that is a rough surface and that is parallel to said first surface of the package substrate, the sealing resin layer comprising a sealing resin such that the semiconductor chip is sealed with the sealing resin; a surface side terminal that is columnar and is formed so as to pass through the sealing resin layer, one end of the surface side terminal being electrically connected to the electrode pad, and another end of the surface side terminal being exposed at said ground surface of the sealing resin layer, said ground surface of the sealing resin layer having a height that is the same as that of said another end surface of the surface side terminal; and connection wire formed on the ground surface of the sealing resin layer.
