Abstract
A multiple, superposed-channel, solid-state, color image sensor of the 'parallel transfer' type includes a plurality of superposed generally 'ladder shaped' channels in a semiconductor substrate. One 'side rail' of the ladder shape provides the channel structure for a multiple, superposed-channel signal handling device, such as a charge coupled shift register. The 'rungs' of the ladder shape provide a plurality of multiple, superposed-channel color image sensing sites, and the other 'side rail' of the ladder shape provides a plurality of superposed 'anti-bloom' drains, one drain per channel. Electrical contact to a buried channel is provided by a V-groove etching technique. A V-groove extending from the surface of the device into the buried channel provides physical access to the buried channel. A conductor, in ohmic contact with the channel, extends from the bottom of the V-groove to the surface of the device to provide electrical contact with the buried channel.
