摘要： A backside illuminated imaging sensor includes a semiconductor having an imaging pixel that can include a photodiode region, an insulation layer, and a reflective layer. The photodiode is typically formed in the frontside of the semiconductor substrate. A surface shield layer can be formed on the frontside of the photodiode region. A light reflecting layer can be formed using silicided polysilicon on the frontside of the sensor. The photodiode region receives light from the back surface of the semiconductor substrate. When a portion of the received light propagates through the photodiode region to the light reflecting layer, the light reflecting layer reflects the portion of light received from the photodiode region towards the photodiode region. The silicided polysilicon light reflecting layer also forms a gate of a transistor for establishing a conductive channel between the photodiode region and a floating drain.

摘要： A technique for fabricating an array of imaging pixels includes fabricating front side components on a front side of the array. After fabricating the front side components, a dopant layer is implanted on a backside of the array. A mask is formed over the dopant layer to selectively expose portions of the dopant layer. Next, the exposed portions of the dopant layer are laser annealed. Alternatively, the mask may be disposed over the backside prior to the formation of the dopant layer and the dopants implanted through the exposed portions and subsequently laser annealed.
