LENS ARRAY AND MANUFACTURING METHOD THEREFOR, SOLID-STATE IMAGING APPARATUS, AND ELECTRONIC APPARATUS

摘要

The present technology relates to a lens array and a manufacturing method therefor, a solid-state imaging apparatus, and an electronic apparatus that can improve the AF performance while suppressing the deterioration of image quality. A lens array includes microlenses that are formed corresponding to phase difference detection pixels that are provided to be mixed in imaging pixels. Each of the microlenses is formed such that a lens surface thereof is a substantially spherical surface, the microlens has a rectangular shape in a planar view and four corners are not substantially rounded, and a bottom surface in vicinity of an opposite-side boundary portion that includes an opposite-side center portion of a pixel boundary portion in a cross-sectional view is higher than a bottom surface in vicinity of a diagonal boundary portion that includes a diagonal boundary portion. The present technology is applicable to a lens array of a CMOS image sensor, for example.
