A new method of forming a photogate structure called a “Charge Snare Device” (CSD) uses only a single layer of polysilicon where prior art methods used two or more layers for constructing the gate nodes. Typical CCD structures utilize three layers of polysilicon and CID structures utilize two layers ...
