SOLID-STATE IMAGING APPARATUS

Abstract:

A solid-state imaging apparatus includes photoelectric conversion regions arranged close to a surface of a semiconductor substrate and a recessed portion provided above each photoelectric conversion region in the semiconductor substrate. Further, the solid-state imaging apparatus includes a light transmissive film embedded in the recessed portion. With this configuration, the performance of the solid-state imaging apparatus is improved, such as improvement of sensitivity and reduction in color mixture.
