Abstract:
A method for memory device fabrication includes forming a plurality of continuous fins on a substrate. An insulator material is formed around the fins. The continuous fins are etched into segmented fins to form exposed areas between the segmented fins. An insulator material is formed in the exposed areas wherein the insulator material in the exposed areas is formed higher than the insulator material around the fins. A metal is formed over the fins and the insulator material. The metal formed over the exposed areas is formed to a shallower depth than over the fins.
