IMAGING DEVICE AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/057806
Kind Code:
A1
Abstract:
The imaging device according to one embodiment of the present disclosure comprises: a semiconductor substrate having a first surface and a second surface facing each other, and a pixel array unit in which a plurality of unit pixels are arranged in an array in the row direction and the column direction; a photoelectric conversion unit that is provided on the second surface side of the semiconductor substrate for each unit pixel and generates a charge according to the amount of received light by photoelectric conversion; a charge holding unit provided on the first surface side of the semiconductor substrate for each unit pixel and holding charges transferred from the photoelectric conversion unit; and a first light-shielding unit provided on the semiconductor substrate, located between the photoelectric conversion unit and the charge holding unit, and that includes a first horizontal light-shielding part extending in the in-plane direction of the semiconductor substrate and a first vertical light-shielding part orthogonal to the first horizontal light-shielding portion, wherein the first vertical light-shielding part consists of a first row light-shielding part and a first column light-shielding part formed respectively along two adjacent sides of a rectangular unit pixel, and is provided for each unit pixel located in every other column and diagonally at 45°, and in plan view, the first horizontal light-shielding part is the end portion located at or near the intersection of the first row light-shielding part and the first column light-shielding part provided for each unit pixel located in every other column and diagonally at 45°.
