Solid-state image pickup element and image pickup apparatus

摘要

A plurality of pixels PD1, PD2 for detecting the phase difference are treated as a pixel group, and a slit 46, which makes incident light entering into each of the pixels of the pixel group PD1, PD2 asymmetrical, is formed in between optical elements (microlenses) 43 formed at an upper layer at the light-entering side of the pixel group PD1, PD2, and in between intermediate refractive-index layers 45. The side faces of the slit 46 are made to be light reflecting faces.

主权项

1. A solid-state image pickup element comprising:
a pixel group configured by a plurality of pixels detecting a phase difference; an optical element formed at an upper layer of a light-entering side of the pixel group; and a groove formed in the optical element; wherein the groove makes incident light entering into each of the plurality of pixels of the pixel group asymmetrical so as to cause a phase difference between the incident light entering into each of the plurality of pixels of the pixel group, and a side surface of the groove is a light reflecting surface.
