Title:
LIGHT DETECTOR AND ELECTRONIC APPLIANCE
Document Type and Number:
WIPO Patent Application WO/2024/111271
Kind Code:
A1
Abstract:
Provided is a light detector capable of more adequately reducing incident light. Specifically, the light detector has a configuration comprising a semiconductor substrate having a plurality of photoelectric conversion parts formed thereon, a plurality of light-collecting parts disposed on the light-entrance-surface side of the semiconductor substrate and having on-chip lenses, and a light reduction structure disposed between some of the on-chip lenses and the semiconductor substrate and having a light-shielding pattern consisting of transmission regions for transmitting light and light-shielding regions for shielding some of the light, wherein the light convergence spot attributable to each light-collecting part is separated from the light reduction structure along a direction orthogonal to the light entrance surface of the semiconductor substrate.
