    • A falling off of a through electrode is inhibited without decreasing a reliability of a semiconductor device including a through electrode. A semiconductor device 100 includes: a silicon substrate 101; a through electrode 129 extending through the silicon substrate 101; and a first insulating ring 130 provided in a circumference of a side surface of the through electrode 129 and extending through the semiconductor substrate 101. In addition, the semiconductor device 100 also includes a protruding portion 146, being provided at least in the vicinity of a back surface of a device-forming surface of the semiconductor substrate 101 so as to contact with the through electrode 129, and protruding in a direction along the surface of the semiconductor substrate 101 toward an interior of the through electrode 129.
    • 在不降低包括通孔的半导体器件的可靠性的情况下,抑制穿通电极的脱落。 半导体器件100包括:硅衬底101; 穿过硅衬底101的通孔电极129; 以及设置在贯通电极129的侧面的周围并延伸穿过半导体基板101的第一绝缘环130.此外,半导体器件100还包括突出部分146,其设置在至少在 半导体衬底101的器件形成表面的背表面与通孔129接触,并沿着半导体衬底101的表面朝向通孔129的内部突出。
