Abstract
A method of nitridation includes cyclically performing the following steps in situ within a processing chamber at a temperature less than about 400° C.: directing an energy flux to a localized region of an unreactive surface of a substrate to convert the localized region of the unreactive surface to a localized reactive region: and selectively nitridating the localized reactive region using a nitrogen-based gas to convert the localized reactive region to a nitride layer.
