Claim Text:
1. A solid-state imaging device comprising: a plurality of pixels, the pixel including a photoelectric conversion unit, a floating diffusion region, an amplifying transistor configured to output a signal based on an amount of electric charge generated by the photoelectric conversion unit, and a resetting transistor configured to reset an input node of the amplifying transistor; a first substrate; and a second substrate, wherein a first insulating film is provided on a first principal surface of the first substrate, wherein the first substrate includes a first pixel region; wherein a plurality of photoelectric conversion units are arranged in the first pixel region; wherein a first element isolation portion is provided in the first pixel region, configured to electrically isolate the plurality of photoelectric conversion units; wherein a second insulating film is provided on the second substrate; wherein the second substrate includes a second pixel region; wherein a plurality of the amplifying transistors and a plurality of the resetting transistors are arranged in the second pixel region; wherein a second element isolation portion is provided in the second pixel region, configured to electrically isolate at least a part of the plurality of the amplifying transistors and at least a part of the plurality of the resetting transistors; wherein an interface of a region where the first element isolation portion is provided, between the first substrate and the first insulating film, is arranged at a first depth with respect to an interface of a region where the photoelectric conversion unit is arranged, between the first substrate and the first insulating film; wherein an interface of a region where the second element isolation portion is provided, between the second substrate and the second insulating film, is arranged at a second depth with respect to an interface of a region where the amplifying transistor is arranged, between the second substrate and the second insulating film; and wherein the first depth is shallower than the second depth.
