Abstract:
1. A semiconductor device having a pattern comprising: an element formed over a first surface of a semiconductor substrate and structuring an integrated circuit; a separation portion formed by embedding an insulation film into a groove dug in the first surface of the semiconductor substrate; a penetrating electrode provided to penetrate from the first surface to a second surface of the semiconductor substrate; and a penetrating separation portion provided so as to surround the penetrating electrode and separate the penetrating electrode from peripheral portion of the semiconductor substrate in a surface of the first surface of the semiconductor substrate and provided to penetrate from the first surface to the second surface of the semiconductor substrate, wherein the penetrating electrode is arranged in an active region surrounded by the separation portion and the penetrating separation portion is spaced away from the penetrating electrode and is not arranged in the active region in the pattern, and wherein the penetrating separation portion comprises an embedded film in a hole penetrating from an upper surface of the separation portion, at the first surface of the semiconductor substrate, to the second surface of the semiconductor substrate and a first insulation film formed so as to cover an outer circumference of the embedded film.
