ZrO 2 MIM 캐패시터의 구조, 표면 형상 및 전기적 특성
The Structure, Surface Morphology and Electrical Properties of ZrO 2 Metal-insulator-metal Capacitors
E-mail:
[ ZrO 2 ] gate dielectric thin films were deposited by radio frequency (rf)-magnetron sputtering and its structure, surface morphology and electrical peoperties were studied. As the oxygen flow rate increases, the surface becomes smoother. The experimental results indicate that a high temperature annealing is desirable since it improves the electrical properties of the ZrO 2 gate dielectric thin films by decreasing the number of interfacial traps at the ZrO 2 /Si interface. The carrier transport mechanism is dominated by the thermionic emission.
