Latest Patents
One of his latest patents is titled "Dual anode AC supply for continuous deposition of a cathode material." This invention provides an apparatus for sputter deposition of an insulating material in a continuous mode of operation. It utilizes at least two sputtering anodes and a cathode connected to a center-tapped conductor to maintain the target cathode at a negative potential with respect to the plasma. The AC power supply drives each anode alternately to an ion collecting state to attract ions and an electron collecting state to attract electrons, ensuring efficient sputtering.
Another significant patent is the "Method and apparatus for substrate biasing in multiple electrode sputtering systems." This invention discloses a method and apparatus for causing ion bombardment of the substrate during sputter deposition. It includes a novel electrical circuit with a center-tapped transformer, allowing a controllable potential to be applied to the substrate relative to the plasma potential without needing an additional power supply. This innovation enhances the sputtering process by enabling continuous discharging of the surface through alternate ion and electron bombardment.
