Abstract

We demonstrate a high-performance TaN SrTiO3 TaN metal-insulator-metal (MIM) radio-frequency (rf) capacitor with good device integrity of very high capacitance density of 44 fFμ m2, small voltage linearity α of 54 ppm V2 at 2 GHz, and a small capacitance reduction 3.5% from 100 KHz to 10 GHz. Such large capacitance density can largely reduce the device size used in rf integrated circuits.
