Yttrium (III) tris(methylcyclopentadienyl) is considered to have the highest vapor pressure of any of the surveyed yttrium compounds. High vapor pressure of the MO is critical for achieving reasonable growth rates using it as an MOCVD precursor. Y(MeCp)₃, combined with H₂O as an oxygen source, is applied for the growth of Y₂O₃ layers by ALD. This precursor produced lower C and H impurity levels and better electrical characteristics in the resulting RE₂O₃ films. Also, this product, combined with tris(cyclopentadienyl)scandium ScCp₃ (Cp = C₅H₅) and H₂O as an oxygen source, has been applied for the growth of amorphous YScO₃ thin films by atomic layer deposition.
