Patent ID: 8067743

Claim:
An imaging apparatus, comprising, an insulating substrate; and a pixel disposed on said insulating substrate, and comprising: a conversion element for converting an optical signal into an electrical signal, said conversion element having a first electroconductive layer, a second electroconductive layer, and a semiconductor layer disposed between and said first electroconductive layer and said second electroconductive layer; a signal transfer switch electrically connected to said first electroconductive layer and disposed between said insulating substrate and said first electroconductive layer; a reset switch electrically connected to said first electroconductive layer and disposed between said insulating substrate and said first electroconductive layer; a bias wiring electrically connected to said second electroconductive layer and disposed over the semiconductor layer; and an insulating layer arranged between said first electroconductive layer and said signal transfer switch, and between said first electroconductive layer and said reset switch, wherein said first electroconductive layer is electrically connected through a common single contact hole formed in said insulating layer to said signal transfer switch and said reset switch, and wherein said bias wiring is disposed at a position not over said common single contact hole.
