Solid-state image pickup element, image pickup device, and method of manufacturing solid-state image pickup element

Abstract

Provided is a solid-state image pickup element that includes a pixel, a light-receiving-surface-sided trench, and a light-receiving-surface-sided shielding member. A plurality of protrusions is formed on the light-receiving surface of the pixel in the solid-state image pickup element. In addition, the light-receiving-surface-sided trench is formed around the pixel having the plurality of protrusions formed, at the light-receiving surface in the solid-state image pickup element. In addition, the light-receiving-surface-sided member is buried in the light-receiving-surface-sided trench formed around the pixel having the plurality of protrusions formed on the light-receiving surface in the solid-state image pickup element. In addition, the photoelectric conversion region of a near-infrared-light pixel expands to the surface side opposed to the light-receiving surface of the photoelectric conversion region of a visible-light pixel. In addition, a trench is further formed inside the pixel at a surface opposed to the light-receiving surface.
