Abstract:
1. An atomic layer deposition method comprising: in an absence of microwave radiation, providing a first precursor material into a reaction chamber and chemisorbing of at least a fragment of the first precursor material on a substrate within the reaction chamber; after the chemisorbing, exposing the chemisorbed material to microwave radiation within the reaction chamber to cleave said chemisorbed material and thereby release a portion of said material while leaving another portion of the material remaining on the substrate; providing a reactant into the chamber and reacting the reactant with the chemisorbed material; and flowing a second precursor material into the reaction chamber and depositing at least a fragment of the second precursor on the chemisorbed material, the flowing and depositing of second precursor being conducted without exposing the second precursor material to microwave radiation.
