Abstract:
A temperature control device (308) for controlling temperature of an upper chamber (312) of a plasma processing apparatus (300) is described. The temperature control device includes a thermally conductive body (334) having an inner surface and an outer surface removably connected with and in thermal communication with the upper chamber of the plasma processing apparatus. The temperature control device also includes a plurality of thermal interface layers (344, 348, 350, 352) in thermal communication with the thermally conductive body wherein at least one layer is a heating element (350); and a cooling element (326) connected with the banded thermally conductive body and thermally coupled with the upper chamber of the plasma processing apparatus wherein the cooling element is configured to conduct a fluidic medium. The temperature control device further includes at least one temperature sensor for sensing temperature of the upper chamber, a temperature control unit for controlling the heating element and the cooling element; and a latching mechanism for securing the temperature control device to the upper chamber.
Abstract:
A method of coating the inner surfaces of gas passages of a gas delivery system for a plasma process system such as a plasma etching system includes (a) flowing a fluidic precursor of a corrosion-resistant material through the gas passages and depositing a layer of the fluidic precursor to completely coat the inner surfaces of the gas passages; (b) removing excess fluidic precursor from the inner surfaces; (c) curing the deposited layer of the fluidic precursor to form a corrosion-resistant material coating.
Abstract:
Aluminum-plated components of semiconductor material processing apparatuses are disclosed. The components include a substrate and an optional intermediate layer formed on at least one surface of the substrate. The intermediate layer includes at least one surface. An aluminum plating is formed on the substrate, or on the optional intermediate layer. The surface on which the aluminum plating is formed is electrically-conductive. An anodized layer can optionally be formed on the aluminum plating. The aluminum plating or optional the anodized layer comprises a process-exposed surface of the component. Semiconductor material processing apparatuses including one or more aluminum-plated components, methods of processing substrates, and methods of making the aluminum-plated components are also disclosed.
Abstract:
An injector provides optical access into a process chamber along an axial path from a diagnostic end point outside the process chamber through an optical access window. A hollow housing body receives first and second process gases, and surrounds the axial path. A sleeve in the body is urged against the body to minimize particle generation, and defines a first gas bore injecting the first process gas into the process chamber. A second gas bore of the sleeve surrounds the axial path for injecting the second process gas into the process chamber, allowing an optical signal to have a desired signal-to-noise ratio (SNR) at the end point. Methods provide a septum in the second bore dividing the second bore into apertures configured to reduce etching of and deposition on the optical access window and to maintain the desired SNR at the diagnostic end point.
