Claim 17:
18. A sequential infiltration synthesis apparatus comprising:
a reaction chamber provided with a substrate holder to hold at least two substrates;
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 and a gaseous second precursor; and,
a sequence controller operably connected to the one or more upstream and downstream reaction chamber valves and being programmed to enable sequential infiltration of an infiltrateable material provided on the two substrates in the reaction chamber with the gaseous first precursor and the gaseous second precursor, wherein the sequence controller provides the 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.
