Apparatus and method for delivering process gas to a substrate processing system

摘要

A method and apparatus for delivering process fluids to a substrate processing system is described herein. In one embodiment, the fluid delivery system may include a first conduit for coupling a first fluid to the substrate processing system with a first flow controller for controlling the flow of the first fluid through the first conduit; a second conduit for coupling a second fluid to the substrate processing system with a second flow controller for controlling the flow of the second fluid through the second conduit; and a third conduit for coupling the second fluid to the substrate processing system with a third flow controller for controlling the flow of the second fluid through the third conduit. The fluid delivery system may be used to deliver processing fluids to a substrate processing system during semiconductor fabrication.
