  • Apparatus and concept for minimizing parasitic chemical vapor deposition during atomic layer deposition
    Patent number: 6305314
    Abstract: A new method and apparatus for avoiding contamination of films deposited in layered depositions, such as Atomic Layer Deposition (ALD) and other sequential chemical vapor deposition (CVD) processes, is taught, wherein CVD-deposited contamination of ALD films is prevented by use of a pre-reaction chamber that effectively causes otherwise-contaminating gaseous constituents to deposit on wall elements of gas-delivery apparatus prior to entering the ALD chamber.
