A MOS or CMOS based photoconductor on active pixel image sensor. Thin layers of semi-conductor material, doped to PIN or NIP photoconducting layers, located above MOS and/or CMOS pixel circuits produce an array of layered photodiodes. Positive and negative charges produced in the layered photodiodes...http://www.google.se/patents/US6809358?utm_source=gb-gplus-sharePatent US6809358 - Photoconductor on active pixel image sensor
