Patent ID: 6902946

Claim:
A method of forming an active pixel sensor comprising the acts of: providing a semiconductor substrate; forming an interconnection structure adjacent the semiconductor substrate said having a first conductive element that passes through the interconnection structure to the substrate; forming a sensor interconnect structure adjacent the interconnection structure; forming at least one pixel electrode adjacent the sensor interconnect structure; depositing an intrinsic layer over the at least one pixel electrode; removing a portion of the intrinsic layer and a portion of the sensor interconnect structure to expose the first conductive element; and after said removing, depositing a conductive contact layer over the intrinsic layer and the exposed first conductive element, wherein an inner surface of the conductive contact layer is physically and electrically connected to the intrinsic layer, and the inner surface of the conductive contact layer is physically connected to the first conductive element to electrically connect the conductive contact layer to the substrate.
