Title:
LIGHT RECEIVING ELEMENT, IMAGING ELEMENT, AND IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/111107
Kind Code:
A1
Abstract:
[Problem] To provide a light receiving element, an imaging element, and an imaging device capable of suppressing reflection of incident light over a wide range of wavelength from that of visible light to that of infrared light. [Solution] The present invention comprises: a photoelectric conversion layer (41) which contains a chemical compound semiconductor material or an organic material; a semiconductor layer (44) which is disposed closer to a light incident surface side than the photoelectric conversion layer (41), contains a chemical compound semiconductor material for preventing recombination of charges generated by photoelectric conversion in the photoelectric conversion layer (41), and is thinner in film thickness than the photoelectric conversion layer (41); a first insulating layer (45) which is disposed closer to the light incident surface side than the semiconductor layer (44), contains silicon nitride, and is lower in refractive index than the semiconductor layer (44); and a second insulating layer (46) which is disposed closer to the light incident surface side than the first insulating layer (45), contains silicon oxide, and is lower in refractive index than the first insulating layer (45).
