20250346990 · 2025-11-13 ·

A magnetron sputtering system including a substrate to be coated and a magnetron sputtering device including at least one rotatable tubular cathode, a mask positioned between the cathode and the substrate and at least one magnet. The magnet is tiltably supported inside the tubular cathode. The system further includes a controller, wherein the controller is configured to control a tilt of the at least one magnet and/or a tilt of the at least one rotatable tubular cathode with respect to the substrate to be coated for tuning coating uniformity on the substrate.

Cylindrical cathode and chamber using same for sputtering

Sputtering system having cylindrical target with sputtering material on exterior surface; magnet arrangement inside the cylindrical target, having first set of magnets arranged on straight row, each having first pole facing interior wall of the target and second pole facing away from the interior wall, second set having plurality of magnets arranged in obround shape around the first set, each magnet having first pole facing away from the interior wall and second pole facing the interior wall; a keeper plate between the first set of magnets and the second set of magnets, such that straight line passing through an axis connecting the first pole and the second pole of a magnet from the second set intercepts the keeper plate prior to reaching the interior wall; and a cover.

Inverted Cylindrical Magnetron (ICM) System and Methods of Use

An Inverted Cylindrical Magnetron (ICM) System and Methods of Use is disclosed herein generally comprising a co-axial central anode concentrically located within a first annular end anode and a second annular end anode; a process chamber including a top end and a bottom end in which the first annular end anode and the second annular end anode are coaxially disposed, whereby the first annular end anode, the second annular end anode, and the central anode form a 3-anode configuration to provide electric field uniformity, and the process chamber including a central annular space coupled to a tube insulator disposed about the central annular space wall; a cathode concentrically coupled to the tube insulator and a target; and a plurality of multi-zone electromagnets or hybrid electro-permanent magnets surrounding the exterior of the process chamber providing a tunable magnetic field.
