ABSTRACT:
Photo sensitive elements formed on a surface of a substrate are arranged in rows and columns. Column conductors for selectively collecting the information contained in the photo elements are diffused along the length of each column in the same surface of the substrate as the photo elements. A barrier region is formed between the photo elements of each column and their associated column conductor for, normally, preventing leakage of charge from the diffused column conductors back into the photo elements. Row conductors, insulated from the surface of the substrate, are disposed transversely to the columns and lie over the rows of photo elements. Driving voltages applied to a row conductor either place the photo elements of that row in a signal collecting mode or else enable the collected signals in the elements of that row to surmount the barrier and flow into their corresponding column conductors.
