Abstract:
A method of forming a spiral-shaped multilayer thin film on a substrate surface, comprising the steps of:(a) providing a sputtering source having a planar end face with a central axis for rotation thereabout, said end face comprising at least one pair of first and second independently and simultaneously operable cathodes positioned in an array about said central axis and including respective first and second sputtering targets comprised of first and second target materials;(b) providing a substrate having a surface for deposition thereon in spaced-apart, facing relation to said first and second sputtering targets;(c) simultaneously sputtering said first and second targets while rotating said end face of said sputtering source about said central axis and maintaining said substrate stationary during said simultaneous sputtering of said first and second targets, thereby simultaneously depositing on said substrate surface material sputtered from said first and second targets to form a spiral-shaped multilayer thin film on said substrate surface, said spiral-shaped multilayer thin film comprising alternating layers of said first and second target materials.
