Abstract
A method of forming an image sensor is disclosed. A partially processed semiconductor wafer is provide, containing p-type and/or n-type regions which are bounded by isolation regions and with gate oxide layers grown on the surfaces upon which gate electrode structures are disposed, some of said gate electrode structures will serve as gate electrodes of image sensor transistors. Ions are implanted to form source/drain structures about the said gate electrode structures, with an extended region for source drains bordering photodiode regions. Ions are implanted to form photodiodes, overlapping the extended bordering source drain regions. A blanket transparent insulating layer is deposited.
