Abstract
PURPOSE:To reduce crosstalk by providing a charge diffusion inhibiting means which inhibits charges generated in a blind layer adjacent to a sensitive layer from being diffused between adjacent sensitive layers. CONSTITUTION:Sensitive layers (charge diffusion inhibiting means) 11 are formed between sensitive layers 4 of a photodiode 3. Those sensitive layers 11 are formed right below spacers 2 and inhibit charges generated in the blind layers from being diffused to other channels and are held at the same potential with a ground electrode 9. Then when X rays are made incident on the scintillator 1, the scintillator 1 generates visible light which is projected on the sensitive layers 4 and blind layers. Then charges are generated at the irradiated parts and generated charges are tried to flow to a place where charge density is low by diffusion, specially, in the blind layers. The sensitive layers 11, however, are formed and P-N junction is formed at the parts, so diffused charges are absorbed by the sensitive layers 11 and flow to the ground side. Consequently, the charges generated in the blind layers are inhibited from being diffused to other channel elements, thereby reducing the crosstalk.
