ABSTRACT:
Multi-spectral planar photodiode pixels are provided in accordance with the present invention for simultaneously detecting multi-colors of infrared radiation. Each multispectral planar photodiode pixel includes a semiconductor substrate layer, a buffer layer of a first conductivity type material deposited on a semiconductor substrate layer, and a first color layer of the first conductivity type material deposited on the buffer layer. The multispectral planar photodiode pixel further includes a barrier layer of the first conductivity type material deposited on the first color layer, a second color layer of the first conductivity type material deposited on the barrier layer, and a cap layer of the first conductivity type material deposited on the second color layer. A first diode comprising a second conductivity type material is formed in the first color layer, and a second diode comprising a second conductivity type material is formed in the second layer.
