摘要:
A method for removing nitrogen containing residues in a plasma processing chamber is provided. A cleaning gas comprising at least one of CO or CO 2 or both is flowed into the plasma processing chamber. A plasma is generated from the cleaning gas, wherein the plasma removes the nitrogen containing residues. The flow of the cleaning gas is stopped.

A system and method are described for depositing a material onto a receiving surface, where the material is formed by use of a plasma to modify a source material in-transit to the receiving surface. The system comprises a microwave generator electronics stage. The system further includes a microwave applicator stage including a cavity resonator structure. The cavity resonator structure includes an outer conductor, an inner conductor, and a resonator cavity interposed between the outer conductor and the inner conductor. The system also includes a multi-component flow assembly including a laminar flow nozzle providing a shield gas, a zonal flow nozzle providing a functional process gas, and a source material flow nozzle configured to deliver the source material. The source material flow nozzle and zonal flow nozzle facilitate a reaction between the source material and the functional process gas within a plasma region.

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.

Embodiments disclosed herein generally include an apparatus for radical-based deposition of dielectric films. The apparatus includes a processing chamber, a radical source coupled to the processing chamber, a substrate support disposed in the processing chamber, and a dual-channel showerhead disposed between the radical source and the substrate support. The dual-channel showerhead includes a plurality of tubes and an internal volume surrounding the plurality of tubes. The plurality of tubes and the internal volume are surrounded by one or more annular channels embedded in the dual-channel showerhead. The dual-channel showerhead further includes a first inlet connected to the one or more channels and a second inlet connected to the internal volume. The processing chamber may be a PECVD chamber, and the apparatus is capable of performing a cyclic process (alternating radical based CVD and PECVD).
