Patent ID: 7897930

Claim:
An imaging apparatus comprising: a pixel region, on a substrate, including a plurality of pixels arranged in a matrix, each pixel having a photoelectric conversion element that converts light into electric charges and a switching element, wherein the photoelectric conversion element has a first electrode layer to which a bias line is electrically connected, a second electrode layer, a semiconductor layer arranged between the first electrode layer and the second electrode layer, and an impurity semiconductor layer arranged between the first or second electrode layer and the semiconductor layer, and wherein the switching element has a gate electrode, a drain electrode, and a source electrode, and transfers, to a signal line, a signal corresponding to the electric charges converted by the photoelectric conversion element, and an electrode which is arranged on a light-incident side of the impurity semiconductor layer and which is either the first electrode layer or the second electrode layer has an opening at least within a region where the semiconductor layer is arranged, and the impurity semiconductor layer has an opening within a region where the opening of the electrode which is arranged on the light-incident side of the impurity semiconductor layer and which is either the first electrode layer or the second electrode layer is arranged.
