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 Si and an aminosilane into the chamber; 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 physisorbed second portion of the first reactant from the substrate; e) injecting a second reactant 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 the non-chemically reacted portion of the second reactant from the chamber.
