Tris(methylcyclopentadienyl)yttrium(III)
Synonym: Y(MeCp)3
CAS Number 329735-72-0 | MDL Number MFCD00145485 | EC Number 630-916-1
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.
