A method and apparatus for cleaning a chamber in a substrate processing system having less reactivity with the chamber walls and the components contained therein. The method includes mixing a diluent gas with a flow of radicals produced by a plasma remotely disposed with respect to the chamber, at a point located between a plasma applicator and the chamber. The apparatus includes a fluid manifold having multiple inlets and an outlet with the outlet being coupled to an intake port of the chamber. One of the inlets are in fluid communication with the plasma applicator, with the remaining inlets being in fluid communication with a supply of the diluent gas. In this fashion, the diluent gas flow and the flow of reactive radicals mix when traveling between the inlets and the outlet to form a gas-radical mixture egressing from the outlet and traversing through the intake port.

The present invention relates to a method and apparatus for delivery of reactants to a substrate processing chamber. An electronically controlled valve assembly is provided for rapid delivery of pulses of reactants to the chamber. The valve assembly comprises a valve body having a valve seat, and at least one gas inlet and one gas outlet below the seat. The piston is selectively movable within the valve body to open and close the valve. In order to actuate the valve assembly, current is sent to a solenoid coil within the valve body. The solenoid coil generates a magnetic field that acts on an adjacent magnetic member. The solenoid coil, magnetic member and piston are arranged such that relative movement of the coil and magnetic member cause the piston to be moved relative to the valve seat.

A resistive heating structure for a processing apparatus such as a chemical vapor deposition chamber. The system includes a resistive heating substrate holder including a support surface and a support shaft, the holder being comprised of a first material. The support surface includes a resistive heating element. The support shaft has a given length, and through bores for allowing a thermocouple to engage the support surface and electrical conductors to couple to the resistive heating element in the support surface. A metallic mounting structure is coupled to the support shaft and secured to the process apparatus to create a sealed environment within the holder and mounting structure to protect the electrical leads and thermocouple from the process environment.
