Abstract

A color and infrared image sensor includes a silicon substrate, MOS transistors formed in the substrate, a stack covering the substrate and including a first photosensitive layer, an electrically-insulating layer, a second photosensitive layer, and color filters. The image sensor further includes electrodes on either side of the first photosensitive layer and delimiting first photodiodes, and electrodes on either side of the second photosensitive layer and delimiting second photodiodes. The first photosensitive layer absorbs the electromagnetic waves of the visible spectrum and of a portion of the infrared spectrum and the second photosensitive layer absorbs the electromagnetic waves of the visible spectrum and gives way to the electromagnetic waves of the portion of the infrared spectrum.
