Patent ID: 7234222

Claim:
A method for configuring a gas distribution channel, said gas distribution channel being configured for introducing a plasma source gas into a plasma processing chamber of a plasma processing system, comprising: providing a metal conduit; providing a thermo-plastic tubular structure; disposing said thermo-plastic tubular structure within said metal conduit; heating said metal conduit, containing said thermo-plastic tubular structure disposed within, to a first temperature; pressurizing said thermo-plastic tubular structure causing said thermo-plastic tubular structure to mechanically couple with said metal conduit wherein an outer surface of said thermo-plastic tubular structure is longitudinally coupled with an inner surface of said metal conduit; cooling said thermo-plastic tubular structure to a second temperature that is below the melting point of thermo-plastic material of said thermo-plastic tubular structure; and injecting a resin material between said metal conduit and the thermo-plastic tubular structure after said cooling.
