1. A gas distribution system comprising:
- a flange;
an opening within the flange to receive a substrate;
a plurality of first gas expansion ports formed within the flange;
a plurality of second gas expansion ports formed within the flange;
a plurality of first gas channels formed within the flange, wherein each of the plurality of first gas channels terminates at one of the first gas expansion ports;
a plurality of second gas channels formed within the flange, wherein each of the plurality of second gas channels terminates at one of the second gas expansion ports;
a plurality of first gas lines coupled to the one or more first gas channels and to a first gas source comprising a first gas;
a plurality of first gas valves coupled to the plurality of first gas lines and the and the one or more first gas channels;
a plurality of second gas lines coupled to the one or more second gas channels and to a second gas source comprising a second gas;
a plurality of second gas valves coupled to the plurality of second gas lines and the and the one or more second gas channels;
a plurality of first conduits; and
a plurality of second conduits,wherein each first conduit is in fluid communication between one of the first gas expansion ports and a reaction chamber,wherein each second conduit is in fluid communication between one of the second gas expansion ports and the reaction chamber,wherein a flowrate of the first gas to each of the first gas expansion ports is independently adjusted using one of the plurality of first gas valves prior to the first gas entering the flange,wherein a flowrate of the second gas to each of the second gas expansion ports is independently adjusted using one of the plurality of second gas valves prior to the second gas entering the flange,wherein a plurality of first gas lines and a plurality of second gas lines are coupled to a top surface of the flange,wherein the first gas and the second gas are not the same gas, andwherein the first gas and second gas mix within the reaction chamber.

Abstract
A gas distribution system, a reactor system including the gas distribution system, and method of using the gas distribution system and reactor system are disclosed. The gas distribution system can be used in gas-phase reactor systems to independently fine tune gas source locations and gas flow rates of reactants to a reaction chamber of the reactor systems.
