Abstract
A solid-state imaging device includes a pixel array where pixels are arranged in a matrix. Each of the pixels includes a photoelectric conversion unit configured to generate a signal charge based on incident light, and an element isolation layer having light-shielding properties and surrounding a periphery of the photoelectric conversion unit. The element isolation layers of adjacent ones of the pixels in a row direction and a column direction are isolated from each other. A charge storage layer and a charge trapping layer are provided in each of regions between the element isolation layers of the adjacent ones of the pixels in the row direction and the column direction. The charge storage layer stores the signal charge. The charge trapping layer reduces incidence of light on the charge storage layer.
