Title:
PHOTODETECTOR AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/181536
Kind Code:
A1
Abstract:
The present disclosure pertains to a photodetector and an electronic apparatus that enable the reduction of surface reflection of an on-chip microlens and the suppression of image quality degradation. Provided is a photodetector that has a plurality of pixels having a photoelectric conversion part, an on-chip microlens formed corresponding to each pixel, and an antireflection film formed on the surface of the on-chip microlens, the antireflection film being configured by stacking a first inorganic film formed of a metal oxide film and a second inorganic film formed on the surface of the first inorganic film and having a refractive index lower than that of the first inorganic film. The present disclosure can be applied, for example, to a CMOS-type solid-state imaging device.
