Abstract
A solid-state imaging device, method for producing solid-state imaging device and electronic apparatus are provided. The solid-state imaging device includes a substrate, with a plurality of pixels formed in the substrate. In addition, a plurality of groups are formed in the substrate, and in particular in pixel isolation regions between adjacent pixels. The grooves extend from a first surface of the substrate towards a second surface of the substrate. An embedded film extends into the grooves. At least some of the grooves include a first stage near the first surface of the substrate and a second stage near the second surface of the substrate that are defined by walls of the grooves, wherein the first stage is wider than the second stage, and wherein a step is present between the first and second stages. In addition, the device includes a light shielding film adjacent the first surface of the substrate that overlies the grooves. A portion of the light shielding film is embedded in the embedded film that extends into the grooves.
