Solid-state imaging device, manufacturing method of solid-state imaging device, and electronic device

Abstract

The present technology provides a solid-state imaging device, a solid-state imaging device manufacturing method, and electronic equipment that can maintain the accuracy of focus detection and suppress the deterioration of the image quality of the image. The solid-state imaging device includes a plurality of pixels including imaging pixels for generating a picked-up image and focus detection pixels for detecting focus. In this solid-state imaging device, the focus detection pixel includes: a microlens; a photoelectric conversion portion that receives light incident from the microlens; a light shielding portion that blocks a part of the light incident on the photoelectric conversion portion; Dark light incident on the photoelectric conversion part is formed as a dimming filter containing black pigment. The present technology can be applied to, for example, CMOS image sensors.

Description

technical field [0001] The present technology relates to a solid-state imaging device, a method of manufacturing the solid-state imaging device, and electronic equipment, and more particularly, to a solid-state imaging device, a method of manufacturing the solid-state imaging device, and electronic equipment capable of maintaining the accuracy of focus detection and suppressing image quality degradation of images. Background technique [0002] As a method for detecting focus in a solid-state imaging device, a so-called split-pupil type phase-difference focus detection method has been used, in which focus detection pixels are generated in conjunction with a sensor passing through an optical system. A pair of image signals corresponding to the image formed by the light beams, and the focus is detected based on the amount of deviation of the pair of generated image signals. [0003] However, since the imaging pixels and the focus detection pixels provided in the pixel area have...

Problems solved by technology

[0006] However, when dichroic filters are formed in focus detection pixels, it may happen that the amount of light necessary for focus detection is reduced, resulting in a decrease in the accuracy of focus detection

In addition, when a half mirror member is provided in a focus detection pixel, it may occur that ghosting occurs due to irregular reflection of incident light, resulting in deterioration of image quality of an image.
