    • The semiconductor device according to the present invention includes a through electrode that penetrates through a silicon substrate, an isolation trench provided to penetrate through the silicon substrate to surround the through electrode, a silicon film in contact with an inner surface of the isolation trench, a silicon film in contact with an outer surface of the isolation trench, and an insulation film provided between the silicon films. According to the present invention, the silicon film within the isolation trench can be substantially regarded as a part of the silicon substrate. Therefore, even when the width of the isolation trench is increased to increase the etching rate, the width of the insulation film becoming a dead space can be made sufficiently small. Consequently, the chip area can be decreased.
    • 根据本发明的半导体器件包括穿透硅衬底的穿透电极,设置成穿过硅衬底以包围通孔的隔离沟槽,与隔离沟槽的内表面接触的硅膜, 与隔离沟槽的外表面接触的硅膜,以及设置在硅膜之间的绝缘膜。 根据本发明,隔离沟槽内的硅膜可以基本上被认为是硅衬底的一部分。 因此,即使增加隔离沟槽的宽度以增加蚀刻速率,也可以使成为死区的绝缘膜的宽度足够小。 因此,可以减小芯片面积。
