Abstract: An electronic camera utilizing a solid-state light sensitive storage device comprised of a sheet of semiconductor material having a large number of very small electrically isolated metal spots on one surface of the sheet each forming a rectifying, capacitive junction of the type referred to as a Schottky barrier. An electron beam is scanned over a surface upon which the metal spots are formed to reverse bias and capacitively charge the rectifying junctions. A light image focused on the other side of the semiconductor slice discharges each discrete capacitor in proportion to the intensity of the light at the location of said discrete capacitor. The current required to recharge each capacitor as the electron beam is scanned produces an output voltage across a load resistance. The light sensitive storage device is fabricated by properly preparing the surface of the substrate and then evaporatively depositing a layer of the metal, e.g. platinum or gold, at a temperature such that the metal nucleates to form a very thin, discontinuous film having discrete electrically isolated microscopic globules.
