Solid-state image pickup apparatus having improved spectral balance
Abstract:
A solid-state image pickup apparatus includes a substrate, a wiring layer, and a waveguide. The substrate is provided with a pixel array portion constituted of a plurality of pixels each having a photoelectric converter that converts incident light into an electrical signal. The wiring layer includes a plurality of wirings and an insulating layer that covers the plurality of wirings that are laminated above the substrate. The waveguide guides light to each of the photoelectric converters of the plurality of pixels, the waveguide being formed in the wiring layer. The waveguide is formed to have a waveguide exit end from which light exits the waveguide so that a distance between the waveguide exit end and a surface of the photoelectric converter that receives light from the waveguide become shorter, as wavelengths of light guided by the waveguide are longer.
