Organometallic lead precursor, in-situ synthesis thereof, lead-titanium based thin film using the same, and preparation method therefor

Abstract

An organometallic lead precursor, represented by following formula: L.sub.x .multidot.Pb(THD).sub.2 ›I! wherein L is an electron donor ligand selected from the group consisting of NR.sub.3 (R=H, CH.sub.3) gas and Cl.sub.2 gas; THD denotes 2,2',6,6'-tetramethyl-3,5-heptanedione; and x is in the range of 0.5 to 2, is prepared by flowing a gas phase electron donor into a bubbler containing bis (2,2',6,6'-tetramethyl-3,5-heptanedione)Pb at a predetermined temperature, to synthesize, in-situ, an adduct. The precursor exhibits a remarkable improvement in volatility and in stability at the vaporization point. Lead-titanium based thin films prepared from the precursor, display superior reproducibility and reliability.
