Abstract:
1. A semiconductor apparatus comprising: a semiconductor device formed to a first surface of a semiconductor substrate; a blocking film provided in a first via-hole, the first via-hole formed with a concave shape to the first surface of the semiconductor substrate; a first via line, in contact with the blocking film, that is connected to an electrode of the semiconductor device in contact with the blocking film; a second via line formed inside a second via-hole, electrically connected with the first via line with the blocking film interposed therebetween and being a part of a wiring formed to a second surface, the second via-hole formed with a concave shape to the second surface opposing the first surface of the semiconductor substrate so as to reach the blocking film, wherein the blocking film includes at least one kind of group 8 element and is formed as being projected to the second via-hole.
