Abstract:
In a liquid crystal display (LCD) fabrication process including a pulsed direct current (DC) sputtering system with a cathode and an anode, method for depositing films comprising:supplying an insulator substrate having a horizontal top surface; supplying a target cathode of a first material; supplying an anode having an electron collection surface; shielding the electron collection surface of the anode from the deposition of a second material; sputter depositing the substrate top surface to form a film of the second material; and, wherein shielding an electron collection surface of an anode from the target first material includes forming an anode with vertical and horizontal ribs, and a single fin having a top surface and a bottom surface to collect electrons, interposed between the anode ribs.
