Abstract

We have fabricated high-κ. TaN/Ir/TiLaO/TaN metal-insulator-metal capacitors. A low leakage current of 6.6 × 10^-7 A/ cm² was obtained at 125 °C for 24-fF/μm² density capacitors. The excellent device performance is due to the combined effects of the high-κ TiLaO dielectric, a high workfunction Ir electrode, and large conduction band offset.
