Patent ID: 8519319

Claim:
An apparatus including a semiconductor device with a substrate, comprising: at least one visible light detection unit coupled to an image signal processing unit, each said visible light detection unit comprising a color filter adapted to transmit a corresponding wavelength region of visible light; at least one infrared light detection unit adapted to detect a wavelength region of infrared light and coupled to said image signal processing unit; and electrical isolation between the at least one light detection unit and the at least one infrared light detection unit, wherein, the at least one infrared light detection unit is positioned deeper within the substrate than the at least one visible light detection unit relative to a side on which light is incident on the semiconductor device, the substrate is an N-type substrate, and a P-N junction of the at least one visible light detection unit has a same ordered arrangement on the N-type substrate relative to a side on which light is incident on the semiconductor device as a P-N junction of the at least one infrared light detection unit.
