TWO-PHASE CHARGE COUPLED DEVICE STRUCTURE

摘要

TWO-PHASE CHARGE COUPLED DEVICE STRUCTURE A semiconductor integrated charge coupled device is disclosed having an optimized minimum bit length for two-phase operation. Minimum spacing between created depletion regions and electrodes is obtained by having different ion implanted doping levels in the structure in correlation to overlying phase electrodes. Also disclosed is means for segmenting a charge coupled device channel with provision for sensing of data in each channel segment to increase the speed of transfer of information from the device. Also disclosed is a novel correlation of transfer or control electrodes of a CCD device with a source of phase clock pulses to provide directionality in a single CCD channel.
