Abstract
Hafnium-based dielectrics have been extensively investigated as a possible replacement for SiO2. Anhydrous Hf/Zr mixed-metal nitrate precursor HfxZr1−x(NO34 (HZN) was successfully synthesized and hafnium zirconate (HfxZr1−O2) thin films were prepared by the chemical vapor deposition (CVD) technique from this precursor. The basal dielectric properties of HfxZr1−O2 films were studied, and C-V curves with negligible hysteresis are achieved.
