Patent ID: 7867894

Claim:
A method for producing a substrate including a semiconductor substrate, a pad provided at one side of the semiconductor substrate and insulated from the semiconductor substrate, and a penetration electrode disposed so as to penetrate the semiconductor substrate at a portion facing the pad, one end part of which is connected to the pad and is insulated from the semiconductor substrate; the method comprising the steps of: forming a metallic film, which is a matrix of the pad, on the semiconductor substrate; forming a through hole in the semiconductor substrate at a portion facing the metallic film at the portion corresponding to an area where the pad is formed; forming a penetration electrode in the through hole; forming a penetration portion, by which the side of the penetration electrode is exposed, in the semiconductor substrate; forming an insulative material so as to fill up at least the penetration portion; and forming the pad by patterning the metallic film after the step of forming the insulative material.
