Abstract
An image sensor (10) has an image sensing element that includes an N-type conducting region (26) and a P-type pinned layer (37). The two regions form two P-N junctions at different depths that increase the efficiency of charge carrier collection at different frequencies of light. The conducting region (26) is formed by an angle implant that ensures that a portion of the conducting region (26) can function as a source of an MOS transistor (32).
