    摘要： Methods and apparatus for processing semiconductor substrates are described. A processing chamber includes a substrate support with an in-situ plasma source, which may be an inductive, capacitive, microwave, or millimeter wave source, facing the substrate support and a radiant heat source, which may be a bank of thermal lamps, spaced apart from the substrate support. The support may be between the in-situ plasma source and the radiant heat source, and may rotate. A method or processing a substrate includes forming an oxide layer by exposing the substrate to a plasma generated in a process chamber, performing a plasma nitridation process on the substrate in the chamber, thermally treating the substrate using a radiant heat source disposed in the chamber while exposing the substrate to oxygen radicals formed outside the chamber, and forming an electrode by exposing the substrate to a plasma generated in the chamber.

    摘要： A substrate processing system has a housing that defines a process chamber. A substrate holder disposed within the process chamber supports a substrate during substrate processing. A gas-delivery system introduces a gas into the process chamber. A pressure-control system maintains a selected pressure within the process chamber. A high-density plasma generating system forms a plasma having a density greater than 1011 ions/cm3 within the process chamber. A radio-frequency bias system generates an electrical bias on the substrate at a frequency less than 5 MHz. A controller controls the gas-delivery system, the pressure-control system, the high-density plasma generating system, and the radio-frequency bias system.

    摘要： A process for removing unwanted deposition build-up from one or more interior surfaces of a substrate processing chamber. According to one embodiment the process comprises performing a substrate processing operation on the substrate within the substrate processing chamber and then transferring the substrate out of the substrate processing chamber; flowing a first etchant gas into a remote plasma source, forming reactive species from the etchant gas and transporting the reactive species into the substrate processing chamber to remove a first portion of the unwanted deposition build-up; and thereafter, flowing a second etchant gas into the substrate processing chamber and forming a plasma within the substrate processing chamber from the second gas in order to remove a second portion of the unwanted deposition build-up.

    摘要： A coil is provided for use in a semiconductor processing system to generate a plasma with a magnetic field in a chamber. The coil comprises a first coil segment, a second coil segment and an internal balance capacitor. The first coils segment has a first end and a second end. The first end of the coil segment is adapted to connect to a power source. The second coil segment has a first and second end. The second end of the first coil segment is adapted to connect to an external balance capacitor. The internal balance capacitor is connected in series between the second end of the first coil segment and the first end of the second coil segment. The internal balance capacitor and the coil segments are adapted to provide a voltage peak along the first coil segment substantially aligned with a virtual ground along the second coil segment.
