Patent ID: 8328980

Claim:
An apparatus to supply a plurality of process fluids for processing a substrate in a semiconductor processing chamber, comprising: a fluid supply network being defined between a crossover valve and a tuning supply valve and a plurality of process fluid supply valves; a tuning fluid supply being connected to the fluid supply network through the tuning supply valve; a plurality of process fluids being connected to the fluid supply network through the plurality of process fluid supply valves; a process chamber having a substrate support, the process chamber further having an edge fluid supply and a center fluid supply, the edge fluid supply connected to the fluid supply network through an edge enable valve and the center supply connected to the fluid supply network through a center enable valve, wherein the crossover valve, edge enable valve, and center enable valve allow one of tuning fluid or process fluids to flow to one of the edge fluid supply or the center fluid supply; and a pumpout pump connected to the edge supply and the center supply through a respective edge pump valve and a center pump valve, wherein the pumpout pump evacuates fluid within the fluid supply network.
