PHOTO-DETECTOR DEVICE AND METHOD OF PRODUCING A PHOTO-DETECTOR DEVICE

摘要

Photo-detector device (100) comprising a plurality of pixels (101a-101b), each pixel comprising an alternating stack of several photodiodes and several electrodes (112, 118a-118c) which are electrically conducting, in which: each photodiode comprises a layer of intrinsic amorphous semiconductor (114a-114c) in contact with a layer of doped amorphous semiconductor (116a-116c) which are distinct from the layers of amorphous semiconductor of the other photodiodes, each photodiode being disposed between two electrodes, and each pair of photodiodes comprising one of the electrodes disposed between these photodiodes, in each pixel, each electrode comprises an electrically conducting portion which is not overlaid on the other electrodes of the pixel and is linked electrically to an interconnection hole (124a-124d) filled with an electrically conducting material, in each pixel, portions (128a-128d) of an electrically conducting material are substantially overlaid on each of said non-overlaid electrode portions.
