A magnetically enhanced HDP-CVD plasma source includes a hollow cathode target and an anode. The anode and cathode form a gap. A cathode target magnet assembly forms magnetic field lines that are substantially perpendicular to a cathode target surface. The gap magnet assembly forms a cusp magnetic field in the gap that is coupled with the cathode target magnetic field. The magnetic field lines cross a pole piece electrode positioned in the gap.

Magnetically Enhanced High Density Plasma-Chemical Vapor Deposition Plasma Source For Depositing Diamond and Diamond-Like Films
20210115553 · 2021-04-22 · ·

A method of sputtering a layer on a substrate using a high-energy density plasma (HEDP) magnetron includes positioning the magnetron in a vacuum with an anode, cathode target, magnet assembly, substrate, and feed gas; applying unipolar negative direct current (DC) voltage pulses from a pulse power supply with a pulse forming network (PFN) to a pulse converting network (PCN); and adjusting an amplitude and frequency associated with the plurality of unipolar negative DC voltage pulses causing a resonance mode associated with the PCN. The PCN converts the unipolar negative DC voltage pulses to an asymmetric alternating current (AC) signal that generates a high-density plasma discharge on the HEDP magnetron. An increase in amplitude or pulse duration of the plurality of unipolar negative DC voltage pulses causes an increase in the amplitude of a negative voltage of the asymmetric AC signal in response to the PCN being in the resonance mode, thereby causing sputtering discharge associated with the HEDP magnetron to form the layer from the cathode target on the substrate. A corresponding apparatus and computer-readable medium are disclosed.
