Solid-state imaging devices and electronic information equipment

Abstract

The present invention relates to a solid-state imaging element and electronic information equipment. In order to receive correct signals in the light receiving part, color mixing is suppressed more effectively. A grid-shaped light-shielding wall (8) is set in the pixel boundary part of the boundary part of the color filter (5a, 5b), so that the height between the microlens (7) and the semiconductor substrate (2) is reduced, and then the light-shielding wall (8) (or reflective wall) height is set to 3 / 4 or more of the thickness of the color filter ( 5 a , 5 b ). In addition, the color filters ( 5 a , 5 b ) are formed to be embedded in the grid-shaped light-shielding walls ( 8 ) (or reflecting walls). Accordingly, color mixing is more effectively suppressed in order to receive accurate signals in the light receiving unit.

Description

technical field [0001] The present invention relates to a solid-state imaging device composed of a semiconductor element that performs photoelectric conversion of image light from a subject to take an image, and a digital video camera and a digital still camera that use the solid-state imaging device as an image input device in an imaging unit. Electronic information equipment such as digital cameras such as cameras, image input cameras such as surveillance cameras, scanners, facsimile devices, TV telephone devices, and mobile phone devices with cameras. Background technique [0002] As such conventional solid-state imaging devices, there are CCD-type solid-state imaging devices and CMOS-type solid-state imaging devices including a mechanism for separating incident light into colors (for example, RGB) in a plurality of wavelength ranges by color filters. Among the performances of a solid-state imaging device for obtaining color images, important performances are light-receiv...

[0019] On the other hand, in the conventional solid-state imaging device 200 disclosed in Patent Document 2, the purpose is to improve the anti-reflection efficiency to prevent the loss of incident light and to improve the photoelectric conversion efficiency. In order to prevent color mixing, each color filter has A light-shielding member 206 is formed at the bottom between 204, and since the height of the light-shielding member 206 is low, it may not be possible to effectively suppress color mixing.
