Patent ID: 10889890

Abstract:
A vacuum treatment apparatus includes a vacuum treatment recipient with a circular opening between an inside and exterior of the recipient. The recipient houses a turntable, which defines a plane (P) along its table surface, is drivingly rotatable around a central axis perpendicular to plane (P), and exhibits a plurality of circular substrates supports. The opening is arranged such that during a turn of the turntable the area of each of the substrate supports and the opening are fully aligned and completely face each other. The vacuum treatment apparatus also includes a PVD deposition source attached to the opening. The PVD source has a a circular material target and a static magnet arrangement. The magnet arrangement is arranged in a plane (M) in parallel to plane (P) and is not rotationally symmetric around a central axis running centrally through the magnet arrangement and being perpendicular to the plane (M).
