Abstract
We fabricate the NiLu2O3 TaN metal-insulator-metal capacitor with a high capacitance density of 7.5 fFmum2, a relatively small quadratic voltage coefficient of capacitance (VCC) of 75 ppm/V}2, a low leakage current of 5times 10-8 Acm}2 at -1 V, and an excellent ten-year reliability with a very low \Delta C/C of 0.51% at 3 V. These small VCC value and good reliability are attributed to a reduction of carrier injection and trapping into the dielectric.
