Claim 9:
10. A fast gas exchange system for a process chamber, comprising:
a fast gas exchange manifold, comprising:
a manifold housing having a plurality of inlets and a plurality of outlets for flowing a plurality of process gases therethrough;
a plurality of mass flow controllers coupled to the manifold housing and configured to flow corresponding ones of the plurality of process gases to a plurality of zones of the process chamber, wherein the mass flow controllers are disposed between the plurality of inlets and the plurality of outlets;
a plurality of first valves coupled to the manifold housing, wherein each of the plurality of first valves is coupled upstream to corresponding ones of the plurality of mass flow controllers via a plurality of inlet lines, wherein at least some of the plurality of inlet lines extend directly from one of the plurality of first valves to two of the plurality of mass flow controllers; and
a plurality of mixing lines extending downstream from the plurality of mass flow controllers to a plurality of outlet lines corresponding with the plurality of outlets;

a gas panel having a plurality of gas sources for supplying the plurality of process gases; and
gas supply lines extending from the plurality of gas sources to the fast gas exchange manifold, wherein each of the gas supply lines include a control valve.
