METHODS AND APPARATUS FOR PHYSICAL VAPOR DEPOSITION (PVD) DIELECTRIC DEPOSITION

Abstract:

Methods and apparatus for reducing burn-in time of a physical vapor deposition shield, including: sputtering a dielectric target having a first dielectric constant to form a dielectric layer upon an inner surface of a shield, wherein the shield includes an aluminum oxide coating having a second dielectric constant in an amount sufficient to reduce the burn-in time, and wherein the first dielectric constant and second dielectric constant are substantially similar.
