Claim Text:
1. An atomic layer deposition (ALD) process for forming a nitrogen-containing thin film on a substrate in a reaction chamber comprising a plurality of deposition cycles, each cycle comprising: providing a pulse of a first vapor phase halide reactant into the reaction chamber to form no more than about a single molecular layer of the reactant on the substrate, wherein the first vapor phase reactant does not comprise transition metal; removing excess first reactant from the reaction chamber; providing a pulse of a second vapor phase reactant to the reaction chamber such that the second vapor phase reactant reacts directly with the first halide reactant on the substrate to form a nitrogen containing thin film, wherein the second vapor phase reactant comprises N(AR removing excess second reactant and reaction byproducts, if any, from the reaction chamber, wherein the nitrogen containing thin film is BN, AlN, GaN or InN.
