Abstract
A noble metal liner and a metal-insulator-metal (MIM) capacitor (MIMCAP) are described along with the methods of manufacture or fabrication. The MIM capacitor includes a liner formed of a thin layer or film of a noble metal, which is only a few nanometers thick, e.g., a thickness in the range of about 0.5 nm to about 5 nm or more. In a finished device such as a MIM capacitor, the noble metal liner is sandwiched between a thicker electrode and the insulator, e.g., a layer or thin film of high or ultra high-k material, thereby providing a cap for the electrode to limit leakage currents in the device.
