Low-temperature organometallic chemical vapor deposition of platinum

Abstract
Impurity‐free, polycrystalline films of platinum have been grown by the decomposition of cyclopentadienyl platinum trimethyl, C pPtM e 3, in hydrogen and a noble gas over silicon or glass substrates heated to 180 °C. The films contain less than 1 at. % of oxygen and carbon, and no other detectable impurities, as measured by x‐ray photoelectron and Auger spectroscopies after argon ion sputtering. Sheet resistivities are 50% greater than sputter‐deposited platinum.
