abstract = {The stabilization of highly reactive amide complexes of
zirconium diethylamide with malonates as chelating ligands
leads to a stable six-coordinated monomeric complex which
shows promise for CVD applications. This novel precursor,
zirconium bis(diethylamido)bis(di-tert-butylmalonato)
zirconium, [Zr(NEt2)(2)(dbml)(2)], has been characterized
and tested in a production-type MOCVD reactor for ZrO2
thin-film deposition. Up to 450 degrees C, the ZrO2 films
are amorphous, and above 475 degrees C films they are
crystalline. Atomic force microscopy (AFM) shows a lower
roughness (similar to 2.5 angstrom) for as-deposited
amorphous films compared to crystalline films (similar to
6.0 angstrom); however, smooth crystalline films can be
obtained by post-deposition annealing of amorphous films.
Electrical properties are investigated for Pt/ZrO2/SiOx/Si
capacitor structures. Relative dielectric permittivity
reaches a bulk value of 24, and leakage currents for
typically 4 nm thick films are below 10(-4) A cm(-2) at a
bias of -1 V Hence, the precursor shows promising properties
for possible application in the deposition of high-k gate
oxide (MIS) and high-k dielectric (MIM) structures.},
