Samsung patents image sensor coating that cuts glare to boost light capture

Samsung has been granted a patent for an image sensor design that uses a special anti-reflection coating to reduce light bouncing off the sensor surface. The coating consists of alternating layers with different light-bending properties, arranged in a specific pattern to let more light reach the sensor's pixels.

Why it mattersThis improvement could lead to sharper photos in low-light conditions by ensuring the camera sensor captures more of the light that hits it.

In the filing’s own words

An image sensor includes: a sensor substrate including a plurality of first pixels configured to sense light of a first wavelength and a plurality of second pixels configured to sense light of a second wavelength; and an anti-reflection element provided on the sensor substrate, wherein the anti-reflection element includes a plurality of low-refractive index patterns and a high-refractive index layer provided between the plurality of low-refractive index patterns and the sensor substrate.

What exactly they claim (claim 1)

1. An image sensor comprising: a sensor substrate including a plurality of pixels, the plurality of pixels being two-dimensionally arranged in a first direction and in a second direction perpendicular to the first direction; and an anti-reflection element provided to face the sensor substrate in a third direction perpendicular to the first direction and the second direction, the anti-reflection element being configured to lower a reflectivity of light incident on the image sensor and provide light to be sensed to the plurality of pixels of the sensor substrate, the anti-reflection element including a high-refractive index layer provided on the sensor substrate and a plurality of low-refractive index patterns provided on the high-refractive index layer and arranged two-dimensionally in the first direction and in the second direction.
