Abstract

Two novel mononuclear mixed alkoxide compounds of Ti and Zr, [Ti(OPr i )2(tbaoac)2] and [Zr(OPr i )2(tbaoac)2], were synthesised and characterised. These complexes are highly soluble and possess superior thermal properties showing promising characteristics as precursors for MOCVD of oxide thin films. Results are presented for thin films, which were deposited in a liquid injection metal-organic chemical vapour deposition production tool. Special emphasis is given to the properties of ZrO2 thin films within MIS structures as proposed for gate oxide applications and to the compatibility of the new Ti precursor with a standard Sr(thd)2 precursor for low temperature deposition of SrTiO3.
