    Abstract: Methods and apparatus for processing a substrate are provided herein. For example, apparatus can include a system for processing a substrate, comprising: a remote plasma source including a supply terminal configured to connect to a power source and an output configured to deliver RF power to a plasma block of the remote plasma source for creating a plasma; and a controller connected to the supply terminal of the remote plasma source and configured to determine, based on a predictive model of the remote plasma source, whether a power at the supply terminal is equal to a predetermined threshold during processing of a substrate, wherein the predictive model includes a correlation of remote plasma performance with delivered RF power at the output, and to control the processing of the substrate based on a determination of the predetermined threshold being met to control processing of the substrate.

    Abstract: A plasma ignition circuit includes a transformer having a primary coil configured to couple an RF power supply. A first secondary coil is configured to couple a remote plasma source (RPS), and a second secondary coil. The plasma ignition circuit further includes a control switch having an input configured to couple the second secondary coil and an output configured to capacitively couple the RPS and a switch controller. The switch controller is configured to upon sensing a secondary RF voltage applied to the second secondary coil in response to an RF voltage applied by RF power supply to the primary coil, enable the control switch to capacitively apply the secondary RF voltage to the RPS to ignite a plasma within the RPS. Upon sensing a drop in plasma impedance when the plasma is ignited, disable the control switch to discontinue applying the secondary RF voltage to the RPS.

    Abstract: Embodiments of the disclosure relate to a remote plasma source for cleaning an exhaust pipe. In one embodiment, an apparatus includes a substrate processing chamber, a pump positioned to evacuate the substrate processing chamber, and an abatement system. The abatement system comprises a plasma gas delivery system positioned between the substrate processing chamber and the pump, the gas delivery system having a first end coupling to the substrate processing chamber and a second end coupling to the pump, a reactor body connected to the gas delivery system through a delivery member, a cleaning gas source connected to the reactor body, and a power source positioned to ionize within the reactor body a cleaning gas from the cleaning gas source. Radicals and species of the cleaning gas react with post-process gases from the substrate processing chamber to convert them into a environmentally and process equipment friendly composition before entering the pump.

    Abstract: Embodiments disclosed herein include a plasma source, an abatement system and a vacuum processing system for abating compounds produced in semiconductor processes. In one embodiment, a plasma source includes a dielectric tube and a coil antenna surrounding the tube. The coil antenna includes a plurality of turns, and at least one turn is shorted. Selectively shorting one or more turns of the coil antenna helps reduce the inductance of the coil antenna, allowing higher power to be supplied to the coil antenna that covers more processing volume. Higher power supplied to the coil antenna and larger processing volume lead to an improved DRE.
