Multiple color detection elevated pin photo diode active pixel sensor
First Claim
1. A color detection active pixel sensor comprising:
- a substrate;
a diode located adjacent to the substrate, the diode electrically connected through an interconnection layer to a first doped region of the substrate, the diode conducting charge when the diode receives photons having a first range of wavelengths; and
a second doped region within the substrate, the second doped region conducting charge when receiving photons having a second range of wavelengths, the photons having the second range of wavelengths passing through the diode substantially undetected by the diode.

Abstract
A color detection active pixel sensor. The color detection active pixel sensor includes a substrate. A diode is electrically connected to a first doped region of the substrate. The diode conducts charge when the diode receives photons having a first range of wavelengths. The substrate includes a second doped region. The second doped region conducts charge when receiving photons having a second range of wavelengths. The photons having the second range of wavelengths passing through the diode substantially undetected by the diode. The substrate can include a doped well within the substrate. The doped well conducts charge when receiving photons having a third range of wavelengths. The photons having the third range of wavelengths pass through the diode substantially undetected by the diode.
