Patent ID: 6967364

Claim:
An imager comprising: a doped layer formed in a substrate having a first surface level; an array of pixel sensor cells formed at least partially in said doped layer, wherein each pixel sensor cell comprises: a photoconversion device, said photoconversion device having a first doped region of a first conductivity type, said first doped region being located at least partially over said first surface level, and a second doped region of a second conductivity type, said second doped region being located beneath said first doped region; a first transistor having a gate which is located adjacent to said first and second doped regions and a first source/drain region having a surface located at approximately a same level as a surface of said second doped region, and a second transistor having a gate which is located adjacent to said first source/drain region and a second source/drain region having a surface located at approximately a same level as a surface of said second doped region; at least one peripheral transistor formed in said substrate; elevated source/drain regions located over said first surface level of said substrate, and signal processing circuitry formed in said substrate and electrically connected to the array for receiving and processing signals representing an image output by the array and for providing output data representing said image.
