Abstract
Provided are a semiconductor apparatus, an imaging device, and an electronic apparatus that improve the gate controllability of a field-effect transistor. The field-effect transistor of the apparatus includes a semiconductor region in which a channel is formed, a gate electrode covering the semiconductor region, and a gate insulating film between the semiconductor region and the gate electrode. The semiconductor region has an upper surface and a first side surface on one side of the upper surface in a gate width direction of the gate electrode. The gate electrode includes a first portion facing the upper surface and a second portion facing the first side surface. The gate insulating film includes a first film portion between the upper surface and the first portion, and a second film portion between the first side surface and the second portion. The second film portion is thickest in a portion close to the upper surface.
