Patent number: 7455884Abstract: A method for atomic layer deposition providing a dispenser unit used to prevent mixing of a precursor gas and an input gas. From the dispenser unit a flow of the input gas is provided over a surface of the workpiece wherein a beam of the electromagnetic radiation is directed into the input gas in close proximity to the surface of the workpiece, but spaced a finite distance therefrom. The input gas is dissociated by the beam producing a high flux point of use generated reactive gas species that reacts with a surface reactant formed on the surface of the workpiece by a direct flow of the precursor gas flown from the dispensing unit. The surface reactant and reactive gas species react to form a desired monolayer of a material on the surface of the workpiece.Type: GrantFiled: January 27, 2004Date of Patent: November 25, 2008Assignee: Micron Technology, Inc.Inventor: Gurtej S.
