Abstract:
An atomic layer deposition method of forming a solid thin film layer containing silicon comprising the steps of:(a) placing a substrate into a chamber; (b) injecting a first reactant containing two or more compounds into the chamber, each said compound containing Si and Cl; (c) chemisorbing a first portion of the first reactant onto the substrate and physisorbing a second portion of the first reactant onto the substrate; (d) removing the non-chemically absorbed second portion of the first reactant from the chamber; (e) injecting a second reactant including NH3 into the chamber; (f) chemically reacting a first portion of the second reactant with the chemisorbed first portion of the first reactant to form a silicon-containing solid on the substrate; and, (g) removing non-reacted portions of the second reactant from the chamber.
