  • Abstract
    DC and RF characteristics of Si/SiO2(~4 mum)/Ti/Pt-HfO2-Al metal-insulator-metal (MIM) devices were investigated with atomic layer-deposited (ALD) high-k HfO2 films. Excellent DC and RF properties were obtained compared to those using either SiO2 or Si3N4. Both high capacitance density and small frequency-dependent capacitance reduction were observed in the MIM capacitors, in which ALD HfO2 was used as an insulator.
