Patent ID: 7736473

Claim:
A method of sputtering in a plasma sputter reactor arranged about a central axis and having a target in opposition to a pedestal supporting a substrate to be sputter coated with a material of said target, including the steps of: selecting different first and second radii from within a radial range based upon a recipe for processing the substrate; a first step of rotating a magnetron about the central axis at the first radius; and a second step of rotating said magnetron at a second radius less than said first radius about said central axis; wherein the magnetron is moved by a magnetron mechanism, comprising: a rotary shaft; a fixed arm fixed to the rotary shaft; a pivoting arm supported on and pivoting relative to the fixed arm and supporting a magnetron to be facing a sputtering target; and a motive source acting exterior to a sputter chamber containing the magnetron and causing the pivoting arm to pivot on the fixed arm.
