  • Patent number: 10453885
    Abstract: The present disclosure relates to a solid-state imaging apparatus and an electronic device capable of reducing a product yield and reliability risk. By forming a contact by forming an opening in an insulating film on a back surface of a peripheral circuit region without connecting a light-shielding metal on the peripheral circuit region to the ground (GND), the light-shielding metal is connected to a Si substrate. Furthermore, a light-shielding metal on a pixel region is connected to the ground (GND). Therefore, by disposing an isolated region (insulating region) where no metal is formed between the light-shielding metal on the pixel region and the light-shielding metal on the peripheral circuit region, the light-shielding metal on the pixel region does not cause a short circuit with the light-shielding metal on the peripheral circuit region. The present disclosure can be applied to, for example, a CMOS solid-state imaging apparatus used for an imaging apparatus such as a camera.
