  • Patent number: 10615201
    Abstract: In manufacturing an image sensor for FPD having an oxide semiconductor TFT as a switching element, a large amount of hydrogen contained in raw gas is diffused in the oxide semiconductor at the time of forming a-Si photo diode (PD) which is a photoelectric conversion element, causing significant variation in the characteristic of TFT which may thereby not operate. In an image sensor in which an oxide semiconductor TFT and a-Si PD are formed on a substrate in this order, a gas barrier film is disposed between the oxide semiconductor TFT and the PD, and the drain terminal (drain metal) of the oxide semiconductor TFT is connected to one terminal (lower electrode) of the PD via connection wiring (bridge wiring) formed on a protective film arranged over the PD.
