Claim 11:
12. A sequential infiltration synthesis apparatus comprising:
a reaction chamber provided with a substrate holder to hold at least one substrate and a first heating system constructed and arranged to control the temperature of the reaction chamber to a process temperature;
a precursor distribution and removal system comprising one or more upstream and downstream reaction chamber valves to provide to and remove from the reaction chamber a gaseous first precursor or a gaseous second precursor; and,
a sequence controller operably connected to the one or more of the one or more of the upstream and downstream reaction chamber valves and being programmed to enable sequential infiltration of an infiltrateable material provided on the substrate in the reaction chamber with the gaseous first precursor and the gaseous second precursor, wherein the sequence controller provides the gaseous first precursor to the reaction chamber with the precursor distribution and removal system while not removing any precursor for a load period LP, resulting in a pressure buildup in the reaction chamber, and terminating the load period LP when the pressure of the gaseous first precursor or the gaseous second precursor in the reaction chamber reaches a desired infiltration pressure,
wherein the one or more of the one or more of the upstream and downstream reaction chamber valves comprises a distribution reaction chamber valve that is upstream of the reaction chamber.
