摘要： A plasma chamber with a plasma confinement zone with an electrode is provided. A gas distribution system for providing a first gas and a second gas is connected to the plasma chamber, wherein the gas distribution system can substantially replace one gas in the plasma zone with the other gas within a period of less than 1 s. A first frequency tuned RF power source for providing power to the electrode in a first frequency range is electrically connected to the at least one electrode wherein the first frequency tuned RF power source is able to minimize a reflected RF power. A second frequency tuned RF power source for providing power to the plasma chamber in a second frequency range outside of the first frequency range wherein the second frequency tuned RF power source is able to minimize a reflected RF power.

摘要： A gas distribution system for supplying different gas compositions to a chamber, such as a plasma processing chamber of a plasma processing apparatus is provided. The gas distribution system can include a gas supply section, a flow control section and a switching section. The gas supply section provides first and second gases, typically gas mixtures, to the flow control section, which controls the flows of the first and second gases to the chamber. The chamber can include multiple zones, and the flow control section can supply the first and second gases to the multiple zones at desired flow ratios of the gases. The gas distribution system can continuously supply the first and second gases to the switching section and the switching section is operable to switch the flows of the first and second gases, such that one of the first and second process gases is supplied to the chamber while the other of the first and second gases is supplied to a by-pass line, and then to switch the gas flows. The switching section preferably includes fast switching valves operable to quickly open and close to allow fast switching of the first and second gases, preferably without the occurrence of undesirable pressure surges or flow instabilities in the flow of either gas.
