Light sensor having a contiguous IR suppression filter and a transparent substrate

A light sensor comprising:

• a substrate having a surface;
• a plurality of photodetectors formed in the substrate and configured to detect light and to provide a signal in response thereto;
• a plurality of color pass filters positioned over the surface and configured to filter visible light to pass light in a limited spectrum of wavelengths to the one or more photodetectors, each color pass filter corresponding to a respective photodetector;
• a first buffer layer positioned over the surface such that the buffer layer at least substantially encapsulates the one or more color pass filters;
• an IR suppression filter disposed over the buffer layer and configured to filter infrared light to at least substantially block infrared light from reaching the plurality of photodetectors;
• a second buffer layer positioned over the IR suppression filter;
• and
• a transparent substrate positioned over the second buffer layer,
• wherein the IR suppression filter comprises a contiguous IR suppression filter disposed continuously over the plurality of color pass filters and the plurality of photodetectors.

A process comprising:

• forming one or more photodetectors in a substrate, the one or more photodetectors configured to detect light and to provide a signal in response thereto;
• forming one or more color pass filters over a surface of the substrate, the one or more color pass filters configured to filter visible light to pass light in a limited spectrum of wavelengths to the one or more photodetectors;
• forming a buffer layer over the one or more color pass filters;
• and
• forming an IR suppression filter on a transparent substrate, the IR suppression filter configured to at least substantially block infrared light from reaching the surface and the transparent substrate configured to facilitate formation of the IR suppression filter,
• wherein the IR suppression filter comprises a contiguous IR suppression filter disposed continuously over the plurality of color pass filters and the plurality of photodetectors.
