摘要： Embodiments disclosed herein generally relate to an apparatus having an anodized gas distribution showerhead. In large area, parallel plate RF processing chambers, mastering the RF return path can be challenging. Arcing is a frequent problem encountered in RF processing chambers. To reduce arcing in RF processing chambers, straps may be coupled to the susceptor to shorten the RF return path, a ceramic or insulating or anodized shadow frame may be coupled to the susceptor during processing, and an anodized coating may be deposited onto the edge of the showerhead that is nearest the chamber walls. The anodized coating may reduce arcing between the showerhead and the chamber walls and therefore enhance film properties and increase deposition rate.

摘要： Embodiments of the invention generally include shield frame assembly for use with a showerhead assembly, and a showerhead assembly having a shield frame assembly that includes an insulator that tightly fits around the perimeter of a showerhead in a vacuum processing chamber. In one embodiment, a showerhead assembly includes a gas distribution plate and a multi-piece frame assembly that circumscribes a perimeter edge of the gas distribution plate. The multi-piece frame assembly allows for expansion of the gas distribution plate without creating gaps which may lead to arcing. In other embodiments, the insulator is positioned to be have the electric fields concentrated at the perimeter of the gas distribution plate located therein, thereby reducing arcing potential.

摘要： Malfunction of a component within an RF-powered plasma chamber is detected by observing an operating condition of the plasma chamber and detecting when the operating condition deviates from a previously observed range bounded by lower and upper limits. The lower and upper limits are determined by observing the minimum and maximum values of that operating condition during the processing of workpieces throughout one or more plasma chamber cleaning cycles immediately preceding the most recent cleaning of the plasma chamber.

The waveguide dielectric includes first and second longitudinal ends and includes first, second, third and fourth sides extending longitudinally between the two longitudinal ends. The first waveguide wall is positioned so that it covers the first side of the waveguide dielectric, and the second waveguide wall is positioned so that it covers the second side of the waveguide dielectric. In operation, electrical power can be supplied to one or both longitudinal ends of the waveguide dielectric, whereby the power can be coupled to a plasma through the exposed sides of the waveguide dielectric.

摘要： Embodiments of a gas diffuser plate for distributing gas in a processing chamber are provided. The gas distribution plate includes a diffuser plate having an upstream side and a downstream side, and a plurality of gas passages passing between the upstream and downstream sides of the diffuser plate. The gas passages include hollow cathode cavities at the downstream side to enhance plasma ionization. The depths, the diameters, the surface area and density of hollow cathode cavities of the gas passages that extend to the downstream end can be gradually increased from the center to the edge of the diffuser plate to improve the film thickness and property uniformity across the substrate. The increasing diameters, depths and surface areas from the center to the edge of the diffuser plate can be created by bending the diffuser plate toward downstream side, followed by machining out the convex downstream side. Bending the diffuser plate can be accomplished by a thermal process or a vacuum process. The increasing diameters, depths and surface areas from the center to the edge of the diffuser plate can also be created computer numerically controlled machining. Diffuser plates with gradually increasing diameters, depths and surface areas of the hollow cathode cavities from the center to the edge of the diffuser plate have been shown to produce improved uniformities of film thickness and film properties.

摘要： The present invention generally includes a plasma enhanced chemical vapor deposition (PECVD) processing chamber having an RF power source coupled to the backing plate at a location separate from the gas source. By feeding the gas into the processing chamber at a location separate from the RF power, parasitic plasma formation in the gas tubes leading to the processing chamber may be reduced. The gas may be fed to the chamber at a plurality of locations. At each location, the gas may be fed to the processing chamber from the gas source by passing through a remote plasma source as well as an RF choke or RF resistor.

摘要： The present invention generally includes a chamber liner spaced from a chamber wall to permit processing gases to be pulled between the chamber liner and the chamber wall when withdrawing gases from the processing chamber. When the vacuum pump is below the susceptor, processing gases will be drawn below the susceptor and may lead to undesired deposition onto process chamber components. Additionally, the processing gases will be pulled past the slit valve opening and potentially deposit within the slit valve opening. When material deposits in the slit valve opening, flaking may occur and contaminate the substrates. By drawing the processing gases along the sidewalls other than the one having the slit valve opening therethrough, undesired deposition on the slit valve opening may be reduced.
