Abstract
Method and system for enhanced charged particle beam processes for carbon removal. With the method and system for enhancing carbon removal, associated method and system for decreasing levels of carbon impurity in depositions, also using a precursor gas in charged particle beam processes (and particularly focused ion beam methodologies), are provided. In a preferred embodiment, the precursor gas comprises methyl nitroacetate. In alternative embodiments, the precursor gas is methyl acetate, ethyl acetate, ethyl nitroacetate, propyl acetate, propyl nitroacetate, nitro ethyl acetate, methyl methoxyacetate, or methoxy acetylchloride.
