Abstract:
A thin film manufacturing method comprising:(a) initially injecting a first reactant into a chamber in which a substrate with chemisorption sites on its surface is loaded, thereby chemically adsorbing a first portion of the first reactant onto the surface of the substrate;(b) removing physisorbed first reactant from the chamber to expose unfilled chemisorption sites on the surface of the substrate;(c) re-injecting the first reactant into the chamber, thereby chemically adsorbing a second portion of the first reactant onto the unfilled chemisorption sites on the surface of the substrate;(d) removing physisorbed first reactant from the chemically adsorbed first reactant;(e) injecting a second reactant into the chamber, thereby chemically adsorbing a first portion of the second reactant onto the surface of the substrate and forming a first portion of a monolayer solid thin film by chemical exchange;(f) removing physisorbed second reactant from the chemically adsorbed first reactant and the chemically adsorbed second reactant; and(g) re-injecting the second reactant into the chamber, thereby chemically adsorbing a second portion of the second reactant onto the surface of substrate and forming a second portion of the monolayer solid thin film by chemical exchange.
