Abstract:
It is possible to reduce resistance variations of a member connecting a through-silicon via to a line and improve wiring reliability. A hole through which the through-silicon via is to be stretched is created and an over-etching process is carried out on a wiring layer including the line. Then, by embedding copper in the hole, the through-silicon via made of the copper can be created. After the through-silicon via has been connected to the line made of aluminum through the member which is a connection area, the connection area is alloyed in a thermal treatment in order to electrically connect the through-silicon via to the line. Thus, it is possible to reduce variations of a resistance between the through-silicon via and the line and also improve wiring reliability as well. The present technology can be applied to a semiconductor device and a method for manufacturing the semiconductor device.

Claim (Index 3):
The semiconductor device according to  claim 2  wherein, during a process of sticking said first semiconductor wafer to said second semiconductor wafer and forming a barrier metal film on a penetration hole through which said through-silicon via penetrates said first semiconductor wafer, an aluminum-oxide film on the surface of said line made of aluminum in said second semiconductor wafer is removed and said contact area is alloyed in order to electrically connect said through-silicon via made of copper to said line made of aluminum.
