Abstract:

A semiconductor plasma processing apparatus used to process semiconductor components comprises a plasma processing chamber, a process gas source in fluid communication with the plasma processing chamber for supplying a process gas into the plasma processing chamber, a RF energy source adapted to energize the process gas into the plasma state in the plasma processing chamber, and a vacuum port for exhausting process gas from the plasma processing chamber. The semiconductor plasma processing apparatus further comprises at least one component wherein the component has a body which has a relative magnetic permeability of about 70,000 or greater and a cold sprayed electrically conductive and nonmagnetic coating on a surface of the body wherein the coating has a thickness greater than the skin depth of a RF current configured to flow therethrough during plasma processing.

Abstract:

Components of semiconductor material processing chambers are disclosed, which may include a substrate and at least one corrosion-resistant coating formed on a surface thereof. The at least one corrosion-resistant coating is a high purity metal coating formed by a cold-spray technique. An anodized layer can be formed on the high purity metal coating. The anodized layer comprises a process-exposed surface of the component. Semiconductor material processing apparatuses including one or more of the components are also disclosed, the components being selected from the group consisting of a chamber liner, an electrostatic chuck, a focus ring, a chamber wall, an edge ring, a plasma confinement ring, a substrate support, a baffle, a gas distribution plate, a gas distribution ring, a gas nozzle, a heating element, a plasma screen, a transport mechanism, a gas supply system, a lift mechanism, a load lock, a door mechanism, a robotic arm and a fastener. Methods of making the components and methods of plasma processing using the components are also disclosed.
