Claim Text:
1. A method of forming a platinum thin film comprising: performing a first atomic layer deposition (ALD) process on a substrate using a first platinum organometallic precursor in a first step and an oxidizing precursor in a second step, the first ALD process excluding a reducing precursor; repeating the first ALD process for a plurality of cycles, the plurality of cycles of the first ALD process at least partially coating the substrate with metallic platinum; performing a second ALD process on the at least partially coated substrate using a second platinum organometallic precursor in a first step and a reducing precursor in a second step, the second ALD process excluding an oxidizing precursor; and repeating the second ALD process for a plurality of cycles, the plurality of cycles of the second ALD process forming a thin film of metallic platinum on the substrate.
