Abstract:
A thin stacked semiconductor device has a plurality of circuits that are laminated and formed sequentially in a specified pattern to form a multilayer wiring part. At the stage for forming the multilayer wiring part, a filling electrode is formed on the semiconductor substrate such that the surface is covered with an insulating film, a post electrode is formed on specified wiring at the multilayer wiring part, a first insulating layer is formed on one surface of the semiconductor substrate, the surface of the first insulating layer is removed by a specified thickness to expose the post electrode, and the other surface of the semiconductor substrate is ground to expose the filling electrode and to form a through-type electrode. A second insulating layer is formed on one surface of the semiconductor substrate while exposing the forward end of the through-type electrode, and bump electrodes are formed on both electrodes.
