Abstract:
1. A method of manufacturing a semiconductor substrate provided with a through hole electrode by which first and second principal sides of said semiconductor substrate communicate with each other, said manufacturing method comprising: (a) forming a first insulating layer on a first principal side of said semiconductor substrate; (b) forming a hole through said semiconductor substrate extending from the second principal side of said semiconductor substrate and to said first insulating layer; (c) forming a second insulating layer on the inside surface of said hole; (d) forming a metal film on said first insulating layer; (e) removing a portion of said first insulating layer between said metal film and said hole in order to expose said metal film to said hole; and (f) filling a conductive material into said hole in order to form a through hole electrode which is electrically connected to said metal film.
