Document Type and Number:
WIPO Patent Application WO/2024/084880
Kind Code:
A1
Abstract:
The present invention suppresses mixing of light. The present invention provides a solid-state imaging device that comprises a pixel array part in which a plurality of pixels including a pixel that is provided with a plurality of photoelectric conversion elements with respect to one on-chip lens are two-dimensionally arranged, wherein: the pixels each comprise a control member; the control member is composed of a first member which has a first refractive index and a second member which has a second refractive index that is lower than the first refractive index; the on-chip lens, the first member, the second member and the photoelectric conversion elements are sequentially stacked in this order; the second member has a first surface that faces the first member, and a second surface that faces the photoelectric conversion elements; the first surface comprises a projected part which protrudes toward the on-chip lens, or a recessed part which is recessed toward the photoelectric conversion elements; and in cases where the first surface comprises the recessed part, the surface is provided with a plurality of relief parts.
