Title:
SOLID-STATE IMAGING ELEMENT, METHOD FOR MANUFACTURING SAME, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/138370
Kind Code:
A1
Abstract:
The present technique pertains to: a solid-state imaging element by which an expanded dynamic range can be realized, by imparting a light receiving sensitivity difference between low sensitivity pixels and high sensitivity pixels, without changing the spectral characteristics; a method for manufacturing the solid-state imaging element; and an electronic device. The solid-state imaging element is provided with a pixel array part on which two types of pixels are arrayed: high sensitivity pixels and low sensitivity pixels with different light receiving sensitivities. The low sensitivity pixels are provided with a gray filter above or below the color filter, said gray filter reducing the transmittance of light in the visible light range by a prescribed ratio. The present technique can be applied, for example, to a solid-state imaging element, etc.
