Abstract
A method of forming a spboron nitride (BN) layer on a surface of a substrate, the method comprising providing first and second precursors at the surface of the substrate, the first precursor being a source of boron and the second precursor being a source of nitrogen; heating the substrate to a temperature greater than a pyrolysis point for either of the first and second precursors; pyrolyzing the first precursor at the surface of the substrate; activating the second precursor at the surface of the substrate with the pyrolyzed first precursor; and adsorbing the pyrolyzed first precursor and the activated second precursor onto the surface of the substrate.
