Abstract:
In the semiconductor device, a semiconductor substrate has first and second surfaces. A circuitry layer is formed over the first surface and a first insulating layer is further formed over the circuitry layer. A second insulating layer including a first insulating element is formed over the second surface. A third insulating layer including a second insulating element different from the first insulating element of the second insulating layer is formed over the second surface with an intervention of the second insulating layer therebetween. A penetration electrode penetrates through the semiconductor substrate, the circuitry layer, the first insulating layer, the second insulating layer and the third insulating layer.

Claim (Index 1):
A method of forming a semiconductor device, the method comprising:\n providing a semiconductor substrate having first and second surfaces opposed to each other; forming a plurality of transistors on the first surface of the semiconductor substrate; forming a first interlayer dielectric film to cover the plurality of transistors and the first surface of the semiconductor substrate; forming a first back insulating layer on the second surface of the semiconductor substrate, the first back insulating layer comprising a first insulating element; forming a second back insulating layer in direct contact with the first back insulating layer, the second back insulating layer comprising a second insulating element different from the first insulating element; forming an opening on the second back insulating layer and sequentially etching the first back insulating layer and the semiconductor substrate through the opening to form a substrate through hole; and forming a through silicon via in the substrate through hole.
