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 5):
The method of  claim 4 , wherein the first portion of the first etch stop layer has a first length that is greater than the first distance.
