Abstract
According to one embodiment, a solid-state imaging device includes a unit cell forming region in a pixel array of a semiconductor substrate, a pixel which is provided in the unit cell forming region and generates a signal charge based on a light signal, and an amplification transistor which is provided in the unit cell forming region and amplifies a potential associated with the signal charge transferred from the pixel to a floating diffusion. The amplification transistor includes a gate electrode having one or more first embedded portions embedded in one or more trenches in the semiconductor substrate through a first gate insulating film.
