Abstract:
1. A sputtering apparatus for forming a film on a substrate by physical gas-phase growth comprising: (a) a vacuum chamber; (b) a cathode unit holding a target set inside the vacuum chamber and provided with a revolving mechanism for controllably revolving the target opposite to the substrate; and (c) a substrate-holding unit inside the vacuum chamber to support the substrate facing the target, wherein the substrate-holding unit has a substrate rotary drive system having a rotating axis for rotating the substrate and a scan drive system having a swing scan axis which is the same as the rotating axis for executing swing scanning of the substrate around the axis of the substrate and wherein the cathode unit revolves and the substrate-holding unit rotates and executes swing scanning to support the substrate facing the target such that a line perpendicular to the surface of the substrate is maintained perpendicular to the surface of the target while sputtering is executed.
