    摘要: A chamber for a physical vapor deposition (PVD) apparatus includes a collimator configured to narrow filter sputtered particles into a beam, an electrostatic chuck configured to support a substrate in the chamber, a shield and a chamber plate. The chamber plate includes a nut plate portion having a plurality of nut plates and a plurality of cavities in the chamber plate that are configured to allow gas to ingress and egress, wherein the cavities and nut plates are provided in equal numbers. The chamber is configured to operate at a target pressure, and the number of nut plates and corresponding number of cavities are determined based on the target pressure.

    摘要: A method of depositing a layer on a substrate includes applying a first magnetic field to a cathode target, electrically coupling the cathode target to a first high power pulse resonance alternating current (AC) power supply, positioning an additional cylindrical cathode target electrode around the cathode, applying a second magnetic field to the additional cylindrical cathode target electrode, electrically coupling the additional cylindrical cathode target electrode to a second high power pulse resonance AC power supply, generating magnetic coupling between the cathode target and an anode, providing a feed gas, and selecting a time shift between negative voltage peaks associated with AC voltage waveforms generated by the first high power pulse resonance AC power supply and the second high power pulse resonance AC power supply. An apparatus includes a vacuum chamber, cathode target magnet assembly, first high power pulse resonance AC power supply, additional electrode, additional electrode magnet assembly, second high power pulse resonance AC power supply, and feed gas.
