摘要: Noble metal films can be deposited by atomic layer deposition (ALD)-type processes. In preferred embodiments, Ir, Pd, and Pt are alternately sequentially contacting a substrate with vapor phase pulses of noble precursor, an oxygen source, hydrogen source. The source is preferably reactive species. Preferably the temperature less than about 200° C. Preferably, 10 seconds.
