Abstract

Capacitance-voltage measurements are reported on MOSC devices with ZrO2 and HfO2 gate dielectrics fabricated using novel zirconium and hafnium alkoxide volatile mononuclear complexes. These complexes are significantly less reactive to air and moisture than existing Zr and Hf alkoxides. Feasibility is shown of using this liquid injection chemical vapour deposition method with these precursors for high-k gate dielectric realisation for submicron MOS devices.
