Abstract:
1. A semiconductor device comprising: a semiconductor substrate having a first-side surface, a second-side surface, and a via hole penetrating said semiconductor substrate from said first-side surface to said second-side surface; an electrode on said first-side surface of said semiconductor substrate and arranged so that a portion of said electrode extends to said second-side surface of said semiconductor substrate through said via hole; and a photosensitive resin formed over said first-side surface of said semiconductor substrate so as to cover at least a portion of said first-side surface including an aperture of said via hole, an area of said at least a portion being larger than an area of said aperture of said via hole, said photosensitive resin filling in said via hole to a depth less than an entire depth of said via hole.
