|Abstract:||Using high-κ Al2O3 doped Ta2O5 dielectric, we have obtained record high MIM capacitance density of 17 fF / μm2 at 100 KHz, small 5% capacitance reduction to RF frequency range, and low leakage current density of 8.9 × 10-7 A/cm2. In combination of both high capacitor density and low leakage current density, a very low leakage current of 5.2 × 10-12 A is calculated for a typical large 10 pF capacitor used in RF IC that is even smaller than that of a deep sub-μm MOSFET. This very high capacitance density with good MIM capacitor characteristics can significantly reduce the chip size of RF ICs.|
