Popis: The authors have studied the leakage characteristics of Ru/Hf/sub x/Si /sub 1-x/O/sub y//Si MOS capacitors projected for advanced CMOS gate technology. Prior to Ru gate electrode deposition, the gate dielectrics were annealed by RTA in the temperature range of 700 - 1000 degC in O/sub 2/. The influence of RTA has been analyzed by X-ray diffraction, X-ray reflectivity and capacitance-voltage techniques. RTA at temperatures ranging from 800 - 900 degC improves the leakage characteristics. Presumably, the Pool-Frenkel mechanism controls the current flow through the oxide with Ru electrode
