Title:
LIGHT DETECTION DEVICE AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/188977
Kind Code:
A1
Abstract:
Provided is a light detection device that maintains a saturation signal volume of one photodiode if dual photodiodes are formed and that can avoid worsening of electronic reading. This light detection device is provided with a semiconductor layer that includes a light incidence surface in which a plurality of pixels are arranged in a matrix and on which light enters the pixels. Each of the plurality of pixels is provided with an inter-pixel separation section, an intra-pixel separation section, a first photoelectric conversion section and a second photoelectric conversion section, a first transfer transistor, and a second transfer transistor. The first photoelectric conversion section and the second photoelectric conversion section are disposed so as to be mutually adjacent with the intra-pixel separation section interposed therebetween in plan view. A vertical gate electrode of the first transfer transistor and a vertical gate electrode of the second transfer transistor are, in plan view, disposed along a diagonal line that joins two corner sections of the pixel so that said vertical gate electrodes sandwich the intra-pixel separation section.
