ABSTRACT:
An embodiment of a MIM capacitor includes a first insulating layer formed over a wafer and a first capacitor plate formed over the wafer within the first insulating layer. The MIM capacitor further includes a second insulating layer formed over the first insulating layer, a capacitor dielectric formed over the first capacitor plate within the second insulating layer and a second capacitor plate formed over the capacitor dielectric within the second insulating layer. A recess is formed in the second capacitor plate below an upper surface of the second insulating layer and a catalytic activation layer is formed in the recess.
