Abstract:
In a solid-state imaging device including an on-chip microlens and a light-receiving part to receive incident light condensed by the on-chip microlens, an optical waveguide extending from an undersurface part of the microlens to the light-receiving part and for guiding the incident light condensed by the microlens to the light-receiving part is formed to be integrated with the microlens. By this, since the incident light condensed by the microlens is incident on the light-receiving part with little loss, the sensitivity is improved.
