Title:
IMAGING DEVICE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/084959
Kind Code:
A1
Abstract:
Provided are: an imaging device capable of reducing noise; and an electronic device using said imaging device. This imaging device is equipped with: a light receiving element; and a readout circuit for reading out an electrical signal obtained through photoelectric conversion in the light receiving element. A field-effect transistor included the readout circuit comprises: a semiconductor layer which has a channel formed therein; a gate electrode which covers the semiconductor layer; and a gate insulator film disposed between the semiconductor layer and the gate electrode. The semiconductor layer has a main surface and a first lateral surface that is situated on one end side of the main surface in the gate-width direction of the field-effect transistor. The gate electrode has: a first region that faces the main surface across the gate insulator film; and a second region that faces the first lateral surface across the gate insulator film. The first lateral surface is a surface in which a crystal plane is the (100) plane or a plane equivalent to the (100) plane.
