Passing access line structure in a memory device |
摘要 |
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. |

1. A method for fabricating a memory device, the method comprising:
forming a plurality of continuous fins on a substrate; forming an insulator material around the fins; segmenting the continuous fins into segmented fins to form exposed areas between the segmented fins; forming an insulator in the exposed areas wherein the insulator in the exposed areas is formed higher than the insulator material around the fins; and forming a metal over the fins and the insulator material. |
