Abstract
A light sensor is described that includes a glass substrate having a diffuser formed therein and at least one color filter integrated on-chip (i.e., integrated on the die of the light sensor). In one or more implementations, the light sensor comprises a semiconductor device (e.g., a die) that includes a semiconductor substrate. At least one photodetector (e.g., photodiode, phototransistor, etc.) is formed in the substrate proximate to the surface of the substrate. The color filter is configured to filter light received by the light sensor to pass light in a limited spectrum of wavelengths (e.g., light having wavelengths between a first wavelength and a second wavelength) to the photodetector. A glass substrate is positioned over the substrate and includes a diffuser. The diffuser is configured to diffuse light incident on the diffuser and to pass the diffused light to the at least one color filter for further filtering.
