发明名称 Semiconductor device
摘要 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.
