Abstract:
1. A method of fabricating a layer on a micro-device workpiece, comprising: inserting a workpiece through a passageway and into a reaction chamber, wherein the passageway includes a duct having a first end open to the chamber and a second end apart from the chamber, and wherein the first end remains open to the chamber while processing the workpiece; reacting a first precursor gas and a second precursor gas in the reaction chamber to form a layer of material on a workpiece; and inhibiting an undesirable concentration and/or phase of the first precursor and/or the second precursor from being in the passageway with a gas conditioning system carried by a door assembly at a second end of the passageway, the gas conditioning system including at least one of (a) a flow port through which a secondary gas flows directly into the passageway, and (b) a heating element.
