Abstract:
1. An atomic layer deposition (ALD) device, comprising: a dispersion assembly configured to disperse gas; an inlet manifold block mounted over the dispersion assembly and having a bore, an internal inert gas channel, a first internal reactant line, and a second internal reactant line, the first and second internal reactant lines being in flow communication with the bore; a first reactant valve mounted on the inlet manifold block and configured to control a supply of a first reactant gas to the first internal reactant line; a first inert gas valve mounted on the inlet manifold block and configured to control a supply of an inert gas from the internal inert gas channel to the first reactant valve; a second reactant valve coupled to the inlet manifold block and configured to control a supply of a second reactant gas to the second internal reactant line; and a second inert gas valve mounted on the inlet manifold block and configured to control a supply of the inert gas from the internal inert gas channel to the second reactant valve.
