Patent ID: 7041200

Claim:
A method of processing a substrate in a magnetron sputtering chamber, the method comprising: (a) placing a substrate in the chamber; (b) providing a deposition shield having a textured surface about the substrate, the textured surface comprising pressed ceramic grains that are shaped and sized to cause the sputtered material to adhere thereto, the ceramic grains having an average grain size of at least about 500 microns; (c) providing an isostatically pressed and sintered tungsten sputtering target facing the substrate, the tungsten target being substantially absent voids and comprising a density of at least about 99.99% of the theoretical maximum; and (d) applying an electrical power to the tungsten target to form a plasma in the chamber while applying a magnetic field adjacent to the tungsten target, whereby the tungsten target is sputtered to deposit sputtered material on the substrate.
