dc.description.abstract | We have investigated the device property dependence of high dielectric-constant (high-kappa) TiLaO epitaxial-Ge/Si n-type metal-oxide-semiconductor (n-MOS) capacitors on different GeO(2) and SiO(2) interfacial layers. Large capacitance density of 3.3 mu F/cm(2), small equivalent-oxide thickness (EOT) of 0.81 nm and small C-V hysteresis of 19 mV are obtained simultaneously for MOS capacitor using ultrathin SiO(2) interfacial layer, while the device with ultrathin interfacial GeO(2) shows inferior performance of larger 1.1 nm EOT and poor C-V hysteresis of 93 mV. From cross-sectional transmission electron microscopy, secondary ion mass spectroscopy, and x-ray photoelectron spectroscopy analysis, the degraded device performance using GeO(2) interfacial layer is due to the severe Ge outdiffusion, thinned interfacial GeO(2) and thicker gate dielectric after 550 degrees C rapid-thermal anneal. | en_US |
