We have fabricated high- κ NiTiZrOTaN metal-insulator-metal (MIM) capacitors. A low leakage current of 3.3× 10-8 A cm2 at -1 V was obtained for a 18 fFμ m2 capacitance density. For a 5.5 fFμ m2 capacitance density device, a small voltage coefficient of capacitance α of 105 ppm V2 and temperature coefficient of capacitance of 156 ppm°C were measured.
