In this paper, high performance ALD HfO 2-Al 2O 3 laminate metal-insulator-metal (MIM) capacitor is demonstrated for the first time with high capacitance density of 12.8 fF/μm 2 from 10 kHz to 20 GHz, low leakage current of 7.45×10 -9 A/cm 2@2V, low VCC (voltage coefficients of capacitance), and excellent reliability. The superior electrical properties and reliability suggest that the ALD HfO 2-Al 2O 3 laminate is a very promising material for MIM capacitors for Si RF and mixed signal IC applications.
