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 1):
A solid state image sensor having a plurality of pixels arranged in a pixel region, the solid state image sensor comprising:\n a first semiconductor substrate having a first main surface and a first rear surface opposite to the first main surface; a first light receiving element formed on the first main surface of the first semiconductor substrate in each of the plural pixels; a first insulating film covering the first rear surface of the first semiconductor substrate; a first conductive connection part penetrating the first insulating film and electrically connected to the first light receiving element; a second semiconductor substrate having a second main surface and a second rear surface opposite to the second main surface; a semiconductor element formed near the second main surface of the second semiconductor substrate; a second interlayer insulating film covering the second main surface of the second semiconductor substrate; and a second conductive connection part embedded in a connection hole in an upper surface of the second interlayer insulating film and electrically connected to the semiconductor element, wherein the first insulting film and the second interlayer insulating film are joined to each other and the first and second conductive connection parts are joined to each other in a joint surface of first and second laminated bodies, the first laminated body including the first semiconductor substrate, first conductive connection, and first insulating film, and the second laminated body including the second semiconductor substrate, second conductive connection part, and second interlayer insulating film.
