Abstract:
A semiconductor device and method of manufacture are provided which utilize an air gap to help isolate conductive structures within a dielectric layer. A first etch stop layer is deposited over the conductive structures, and the first etch stop layer is patterned to expose corner portions of the conductive structures. A portion of the dielectric layer is removed to form an opening. A second etch stop layer is deposited to line the opening, wherein the second etch stop layer forms a stepped structure over the corner portions of the conductive structures. Dielectric material is then deposited into the opening such that an air gap is formed to isolate the conductive structures.

Claim (Index 8):
A method of manufacturing a semiconductor device, the method comprising:\n depositing a barrier layer into an opening within a dielectric layer over a substrate, the barrier layer comprising a sidewall facing away from an interior of the opening; filling a remainder of the opening with a conductive material, the conductive material having a first width; depositing a first etch stop layer over the conductive material; removing a first portion of the first etch stop layer and a second portion of the dielectric layer to expose both the sidewall of the barrier layer and a surface of the conductive material, wherein the surface of the conductive material has a second width less than the first width; depositing a second etch stop layer to cover the surface of the conductive material and the sidewall of the barrier layer; and depositing a dielectric material over the second etch stop layer, wherein the depositing the dielectric material forms a void and wherein a first line extends through the void, the dielectric material, the sidewall, and the conductive material, the first line being parallel with a major surface of the substrate.
