Abstract
A reliable metal insulator metal (MIM) capacitor is disclosed. The MIM capacitor is disposed over at least an interlevel dielectric (ILD) layer of a plurality of ILD layers with interconnects disposed over a substrate. The MIM capacitor includes a capacitor dielectric disposed between top and bottom metal capacitor electrodes. The edges of the top metal electrode at the interface with the capacitor dielectric are rounded. The rounded edges of the top capacitor electrode at the interface with the capacitor dielectric reduce edge electric field, thereby improves time-dependent dielectric breakdown (TDDB) reliability of the capacitor.
