Latest Patents

One of his key patents is the "Cylindrical magnetron shield structure." This invention presents an improved shield structure for use in a sputtering apparatus for depositing a film on a substrate. The cylindrically shaped shield structure extends over the ends of a cylindrical sputtering target and features at least one annular structure that interrupts or suppresses the movement of any arc that might otherwise travel across its outside surface. In a preferred embodiment, the annular structure is a groove capable of trapping any such arc and preventing its escape. Additionally, the improved shield structure is electrically isolated to inhibit the formation of severe arcs between it and the cathodic target. This innovative design enhances the overall performance and safety of sputtering processes.
