Abstract:
A target for installation in a vacuum chamber for processing a substrate by causing sputtering material to be ejected from the target onto said substrate, comprisinga disk-shaped section having two planar surfaces and on outer periphery, said disk-shaped section having at least one radially-inward step proximate said outer periphery, a continuous ring configured backing plate with an adapter having an inner radial flange having at least one groove therein to accommodate an o-ring, said radial flange being disposed in a mating relationship with said radially-inward step thereby preventing leakage into said vacuum chamber at the interface of said adapter and said vacuum chamber, said target being manufactured homogeneously of said sputtering material, and said disk-shaped section defining threaded holes proximate said outer periphery of said disk-shaped section.
