Abstract:
In a solid state image sensor having two semiconductor substrates or more laminated longitudinally, electrical connection between the semiconductor substrates is made by a fine plug. An insulating film covering a first rear surface of a semiconductor substrate having a light receiving element, and an interlayer insulating film covering a second main surface of a semiconductor substrate mounting a semiconductor element are joined to each other. In its joint surface, a plug penetrating the insulating film and a lug embedded in a connection hole in an upper surface of the interlayer insulating film are joined, and the light receiving element and the semiconductor element are electrically connected through the plugs.

Claim (Index 15):
The manufacturing method of a solid state image sensor according to  claim 13 , further comprising:\n preparing a second semiconductor substrate during the (b), the second semiconductor substrate having a second light receiving element and a fifth insulating film that covers the second rear surface, the semiconductor element being the second light receiving element that is formed on the second main surface of the second semiconductor substrate in each of the plural pixels; (a1) preparing a third semiconductor substrate, the third semiconductor substrate having a third main surface and a third rear surface opposite to the third main surface, and having a third light receiving element formed on the third main surface, and a third interlayer insulating film covering the third main surface; (c1) forming a fifth conductive connection part penetrating the fifth insulating film and electrically connected to the second light receiving element; (d1) forming a second connection hole in an upper surface of the third interlayer insulating film and then forming, in the second connection hole, a sixth conductive connection part electrically connected to the third light receiving element; and (e1) joining, after the (c1), (d), and (d1), a lower surface of the fifth insulating film and the upper surface of the third interlayer insulating film to each other and joining a lower surface of the fifth conductive connection part and an upper surface of the sixth conductive connection part to each other to laminate the second and third semiconductor substrates.
