Claim:
1. A method for forming a metal-insulator-metal capacitor in a replacement metal gate module, comprising: providing a gate cap formed on a gate; forming a plurality of recesses by forming a plurality of voids in the gate cap and forming a plurality of gate recesses in the gate under the plurality of voids, a remaining portion of the gate forming a first electrode of the capacitor; depositing a dielectric on remaining portions of the gate cap and the remaining portion of the gate; depositing a conductive material on the dielectric; and removing a plurality of portions of the dielectric and a remaining portion of the conductive material to expose a plurality of remaining portions of the dielectric and a plurality of remaining portions of the conductive material, the plurality of remaining portions of the dielectric forming at least a portion of an insulator of the capacitor and the plurality of remaining portions of the conductive material forming a second electrode of the capacitor.
