2,2,6,6-Tetramethyl-3,5-heptanedionate yttrium(III) is conventional precursor for the growth of Y-containing high temperature superconductor layers by MOCVD and electroluminescent Y2O3. This product was applied as a precursor of MOCVD of Y-containing multi-component oxide thin films. Thin films of Y2O3 were deposited on Si(1 0 0) by radical-enhanced atomic layer deposition (ALD), using Y(TMHD)3 and O radicals. The results demonstrate that radical-enhanced ALD is a viable technique for conformal low-temperature deposition of stoichiometric and smooth metal oxide thin films with minimal carbon contamination.
