Abstract
Crystalline titanium dioxide films were deposited on silicon (100) at temperatures as low as 184 °C using the volatile molecular precursor, tetranitratotitanium(IV). Deposition rates in a low pressure chemical vapor deposition (LPCVD) reactor operated at 230 - 500 °C with a precursor vessel temperature at 22 °C were typically 4 nm/min. The effect of deposition temperature and annealing conditions on morphology are shown. Following post-deposition annealing in oxygen and hydrogen, Pt/TiO2/Si/Al capacitors were fabricated and exhibited dielectric constants in the range of 19 - 30 and leakage current densities as low as 10-8 Amp/cm2.
