Abstract:
1. A semiconductor device comprising: a substrate, the substrate comprising a first surface and a second surface, the second surface is another side of the first surface; a conductive pattern located on the first surface side of the substrate; a through-hole formed in the substrate and located over the conductive pattern; an insulating layer located at a bottom surface of the through-hole, the bottom surface is located on the first surface side; an opening pattern formed in the insulating layer, a width of the opening pattern is smaller than a width of a bottom of the through-hole, and the conductive pattern is exposed to the bottom surface of the through-hole; a through-electrode formed in the opening pattern and in the through-hole, so as to be connected to the conductive pattern; and a bump located on the second surface and formed integrally with the through-electrode.
