发明名称 In situ dry cleaning process for poly gate etch
摘要 The present invention provides a method for cleaning a contaminated chamber used in the manufacture of semiconductor devices. In one embodiment, the method comprises the steps of injecting, under pressure, a gas mixture of a fluorine-containing gas and an inert gas into the contaminated chamber, radiating the contaminated chamber with a radio frequency during the step of injecting, and removing volatile by-products or solid particulates from the contaminated chamber by performing pump-purge cycles within the contaminated chamber.
