摘要： Plasma ignition and cooling apparatus and methods for plasma systems are described. An apparatus can include a vessel and at least one ignition electrode adjacent to the vessel. A total length of a dimension of the at least one ignition electrode is greater than 10% of a length of the vessel's channel. The apparatus can include a dielectric toroidal vessel, a heat sink having multiple segments urged toward the vessel by a spring-loaded mechanism, and a thermal interface between the vessel and the heat sink. A method can include providing a gas having a flow rate and a pressure and directing a portion of the flow rate of the gas into a vessel channel. The gas is ignited in the channel while the remaining portion of the flow rate is directed away from the channel.

摘要： A particle trap for a remote plasma source includes a body structure having an inlet for coupling to a chamber of a remote plasma source and an outlet for coupling to a process chamber inlet. The particle trap for a remote plasma source also includes a gas channel formed in the body structure and in fluid communication with the body structure inlet and the body structure outlet. The gas channel can define a path through the body structure that causes particles in a gas passing from a first portion of the channel to strike a wall that defines a second portion of the gas channel at an angle relative to a surface of the wall. A coolant member can be in thermal communication with the gas channel.

摘要： A system for producing excited gases for introduction to a semiconductor processing chamber. The system includes a plasma source for generating a plasma. The plasma source includes a plasma chamber and a gas inlet for receiving process gases from a gas source. A gas flow rate controller is coupled to the gas inlet for controlling an inlet flow rate of the process gases from the gas source to the plasma chamber via the gas inlet. The system includes a control loop for detecting a transition from a first process gas to a second process gas and for adjusting the inlet flow rate of the second process gas from about 0 sccm to about 10,000 sccm over a period of time greater than about 300 milliseconds to maintain transient heat flux loads applied by the plasma to an inner surface of the plasma chamber below a vaporization temperature of the plasma chamber.
