Abstract:
A gas supply assembly is described for delivery of gas to a plasma flood gun. The gas supply assembly includes: a fluid supply package configured to deliver inert gas to a plasma flood gun for generating inert gas plasma including electrons for modulating surface charge of a substrate in ion implantation operation; and cleaning gas in the inert gas fluid supply package in mixture with the inert gas, or in a separate cleaning gas supply package configured to deliver cleaning gas to the plasma flood gun concurrently or sequentially with respect to delivery of inert gas to the plasma flood gun. A method of operating a plasma flood gun is also described, in which cleaning gas is introduced to the plasma flood gun, intermittently, continuously, or sequentially in relation to flow of inert gas to the plasma flood gun. The cleaning gas is effective to generate volatile reaction product gases from material deposits in the plasma flood gun, and to effect re-metallization of a plasma generation filament in the plasma flood gun.

Claim (Index 17):
The method of  claim 13 , wherein the cleaning gas is flowed to the plasma flood gun in mixture with the inert gas.
