    Abstract: An interdigitated structure may include at least one first metal line, at least one second metal line parallel to the at least one first metal line and separated from the at least one first metal line, and a third metal line contacting ends of the at least one first metal line and separated from the at least one second metal line. The at least one first metal line does not vertically contact any metal via and at least one second metal line may vertically contact at least one metal via. Multiple layers of interdigitated structure may be vertically stacked. Alternately, an interdigitated structure may include a plurality of first metal lines and a plurality of second metal lines, each metal line not vertically contacting any metal via. Multiple instances of interdigitated structure may be laterally replicated and adjoined, with or without rotation, and/or vertically stacked to form a capacitor.

    Abstract: A method of fabricating a MIM capacitor is provided. The method includes providing a substrate including a dielectric layer formed on a first conductive layer and a second conductive layer formed over the dielectric layer, and patterning a mask on the second conductive layer. Exposed portions of the second conductive layer are removed to form an upper plate of a MIM capacitor having edges substantially aligned with respective edges of the mask. The upper plate is undercut so that edges of the upper plate are located under the mask. Exposed portions of the dielectric layer and the first conductive layer are removed using the mask to form a capacitor dielectric layer and a lower plate of the MIM capacitor having edges substantially aligned with respective edges of the mask.
