Tris(ethylcyclopentadienyl)yttrium,combined with H2O vapor as oxygen source, was used for the deposition of  yttria Y2O3 thin films on Si by ALD; the precursor evaporation conditions were 120°C/ 0.6-2 mbar. Film growth kinetics was investigated; the growth rate was constant with number of deposition cycles, at optimal ALD conditions being 1.7±0.1 Å/cycle. However, the gradual increase in growth rate was observed when increasing the reactor temperature from 200 to 400°C, with a narrow plateau at ca.~250–285°C. Y2O3 films were stoichiometric with no detectable C contamination as per XPS data); as-deposited Y2O3 layers were polycrystalline (according to glancing incidence XRD). See links below
