Patent ID: 7126127

Claim:
An image pick-up apparatus in which a plurality of pixels, each comprising a pair of a semiconductor conversion elements for converting an incident electromagnetic wave to an electric signal and a thin film transistor connected to said semiconductor conversion element, is arranged in a two-dimensional manner on a substrate, said image pick-up apparatus including gate wiring to which gate electrodes of thin film transistors of a plurality of pixels arranged in one direction are commonly connected, and signal wiring to which source electrodes or drain electrodes of thin film transistors of a plurality of pixels arranged in a direction different from the one direction are commonly connected on said substrate, wherein a protection layer is arranged so as to cover said thin film transistors, said gate wiring and said signal wiring, and the protection layer is removed from at least a part or whole of a region in which a through hole and the semiconductor conversion element are formed, further comprising insulating layers under said protection layer, said insulating layers formed at the same time as that of gate insulating layers of said thin film transistors, wherein said insulating layers are removed similarly to said protection layer in at least parts of or all of said regions in which said semiconductor conversion elements are formed.
