  • Patent number: 11373958
    Abstract: Provided is a semiconductor device that includes a semiconductor substrate, an interconnection layer that is formed on a first face of the semiconductor substrate, at least one of a structural element that is formed to the interconnection layer, or a structural element that is formed in the semiconductor substrate from the first face side of the semiconductor substrate, a semiconductor-through-electrode that is positioned and formed, from a second face side of the semiconductor substrate opposite to the first face, so as to have a predetermined positional relationship with respect to the structural element, and a metallic-diffusion-preventing insulating layer that is formed from the first face side of the semiconductor substrate in a position, and with a shape, surrounding the semiconductor-through-electrode in the semiconductor substrate.

  • Publication number: 20220013557
    Abstract: There is provided a solid-state imaging device having a configuration suitable for high integration. The solid-state imaging device includes a semiconductor layer, a photoelectric converter, a storage capacitor, and a first transistor. The photoelectric converter is provided in the semiconductor layer, and generates an electric charge corresponding to a received light amount by photoelectric conversion. The storage capacitor is provided on the semiconductor layer, and includes a first insulating film having a first electrical film thickness. The first transistor is provided on the semiconductor layer, and includes a second insulating film having a second electrical film thickness larger than the first electrical film thickness.
