Title:
IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/018934
Kind Code:
A1
Abstract:
Provided is an imaging device capable of suppressing the generation of scattered light. The imaging device comprises: a semiconductor substrate having a first surface onto which light falls and a second surface located on the opposite side of the first surface; a plurality of pixels provided on the semiconductor substrate and performing photoelectric conversion on the light; a pixel separation section provided on the semiconductor substrate and separating one pixel and another pixel, which are adjacent to each other, among the plurality of pixels; and a first protrusion that is provided on the semiconductor substrate and protrudes from the pixel separation portion to the inside of the pixel. The first tip of the first protrusion has a first portion located on the first surface side. The first portion has a material or structure that absorbs light to a greater degree than the pixel separation portion.
