abstract = {Pb-Ti-O films were prepared by liquid-injection atomic
layer deposition (ALD) using H2O as oxygen source after
evaluating Ti precursors with different beta-diketonate type
ligands, Ti(OC3H7)(2)(C11H19O2)(2) [Ti(Oi-Pr)(2)(DPM)(2)]
and Ti(OC5H11)(2)(C10H17O2)(2) [Ti(Ot-Am)(2)(IBPM)(2)],
dissolved in ethylcyclohexane. For both Ti precursors, the
apparent thermal activation energy of the deposition rate of
TiOx films increased at a deposition temperature of about
380 degrees C, and the deposition rate of TiOx films grown
at 300 degrees C saturated against the volume of injected Ti
precursors. Ti(Oi-Pr)(2)(DPM)(2) was selected for the
subsequent Pb-Ti-O film deposition because of its high
precursor efficiency and the low temperature dependence of
the deposition rate. Pb-Ti-O films were prepared using
Ti(Oi-Pr)(2)(DPM)(2) and Pb(C12H21O2)(2) [Pb(TMOD)(2)] at
deposition temperatures of 240 and 300 degrees C. The
deposition rates of Pb and Ti in the Pb-Ti-O process were
higher than those in binary PbO and TiOx processes under the
same deposition conditions. The deposition rate of Pb in the
Pb-Ti-O process showed a linear increase in response to the
injected Pb precursor volume, which was different from the
saturated deposition rate of the PbO process. The interface
chemistry between the precursors and predeposited cation
layers has critical impact on the self-regulated growth
mechanism in the multicomponent oxide ALD. (c) 2006 The
