Title:
SOLID-STATE IMAGE-PICKUP DEVICE, METHOD FOR PRODUCING SAME, AND ELECTRONIC EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2014/141991
Kind Code:
A1
Abstract:
The present technique pertains to a solid-state image-pickup device configured so that oblique incidence light properties of image pickup pixels and AF properties of phase difference detection pixels can be made excellent, to a method for producing the same, and to electronic equipment.
A solid-state image-pickup device includes: a plurality of image pickup pixels arranged two-dimensionally in matrix; and phase difference detection pixels that are scattered among the image pickup pixels. The solid-state image-pickup device further includes: first microlenses that are formed so as to correspond to the image pickup pixels, respectively; a flattening film that is formed on the first microlenses and has a refractive index lower than that of the first microlenses; and second microlenses that are formed on the flattening film, only at positions above the phase difference detection pixels. The present technique can be applied to, for example, a CMOS solid-state image-pickup device.
