Abstract
A method for making a metal-insulator-metal (MIM) capacitors by etching a dielectric layer to form a via or contact hole, a tub, and a trench in the dielectric layer; depositing conformal metal in the via or contact hole, the tub, and the trench, wherein deposited conformal metal forms a via or contact in the via or contact hole; depositing a bottom electrode metal in the tub to form a bottom electrode of a metal-to-metal (MIM) capacitor; removing bottom electrode metal from the bottom electrode to form a dish-shape upper surface; depositing an insulator material on the bottom electrode to form an insulator layer of the MIM capacitor; and depositing a top electrode metal on the insulator layer to form a top electrode of the MIM capacitor.
