Aluminium acetylacetonate and synthetic air were applied for the atmospheric pressure hot-wall MOCVD-growth of Al2O3 thin films on stainless steel substrates. This product was used as a precursor for the deposition of carbonaceous crystalline Al2O3 films on Si(100) by LP MOCVD, as well as on stainless steel, and TiN-coated cemented carbide substrates by LP MOCVD in the absence of oxidant gas. Al(acac)3 was applied for the growth of Al2O3 films on Si(111) substrates at varying temperatures by MOCVD. One more application is as a nontoxic and easy-to-handle precursor for the deposition of amorphous Al2O3 thin films on glass and Si(100) substrates by a low-temperature atmospheric-pressure CVD.
