Title:
IMAGE CAPTURE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/015011
Kind Code:
A1
Abstract:
An image capture device according to an embodiment of the present disclosure is provided with: a photoelectric conversion unit provided on the inside of one major surface of a semiconductor substrate; a transfer gate electrode which includes a first electrode portion extending in a columnar shape from the one major surface of the semiconductor substrate in a depth direction, and a second electrode portion further extending in a columnar shape from the first electrode portion in the depth direction, and which forms a transfer path for reading charges obtained by photoelectric conversion performed by the photoelectric conversion unit; and a first conductivity-type region including a first conductivity-type impurity and provided laterally of the transfer gate electrode. The width of the second electrode portion in at least one direction in the plane of the one major surface is smaller than the width of the first electrode portion in the one direction. The first conductivity-type region is provided at least in a region under the first electrode portion and laterally of the second electrode portion in the one direction.
