Abstract:
A method of forming a metal-insulator-metal (MIM) capacitor, comprising:providing a workpiece; depositing an inter-level dielectric ILD layer over the workpiece; forming a first pattern in the ILD layer; forming a second pattern in the ILD layer; and then depositing and patterning a layer of photoresist such that said first pattern is exposed and said second pattern is covered; disposing a first conductive layer over the first pattern of the ILD layer; and then removing said patterned layer of photoresist to expose said second pattern; disposing a second conductive layer over the exposed second pattern of the ILD layer; disposing a first dielectric layer over at least the second conductive layer; and disposing a third conductive layer over the first dielectric layer, wherein the second conductive layer, first dielectric layer and third conductive layer over the second pattern form a first MIM capacitor.
