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 10):
A method for manufacturing a solid-state imaging device of a rear-surface radiation type, said method comprising\n a semiconductor-device manufacturing method including\n a process of alloying a contact area in order to connect an electrode to a line in a semiconductor device whereby, in said process, said contact area shared by said electrode and said line is alloyed in order to electrically connect said electrode and said line to each other in a second semiconductor wafer, which includes logic circuits and lines, and a first semiconductor wafer which includes photoelectric conversion sections and lines.
