Y(iPrCp)3 is used as a precursor for atomic layer deposition (ALD) and chemical vapor deposition (CVD/MOCVD) of yttrium-containing thin films. Its high purity and stable, controlled reactivity make it well suited to depositing yttrium oxide (Y2O3) and related layers used in semiconductor device fabrication, high-k dielectrics, and advanced-materials research. By enabling precise, layer-by-layer control of film composition, it supports consistent thin-film growth in both production and laboratory settings.
