Abstract
A solid state image sensing device comprises an array of picture sensing elements which are MOS transistors formed on a bulk of semiconductor material. The transistors are of a V-MOS configuration and have respective sources, V-shaped gates, and drains. The source-to-bulk diode of a V-MOS picture sensing element functions as a photodiode and is disposed near the surface of the array to receive a respective portion of imagewise illumination. In a preferred embodiment, the drain of the V-MOS picture sensing element is buried in the bulk directly beneath its respective source. The source, in conjunction with its gate, acts as a multiplex switch for the photodiode.
