Abstract
A semiconductor structure includes a contact over a substrate, an interlayer dielectric (ILD) layer including a first region disposed directly above the contact and a second region disposed adjacent to the first region, first conductive features embedded in the first region and separated by a first distance, a dielectric layer embedded in the ILD layer and disposed between the first conductive features in the first region, and second conductive features disposed in the second region and separated by a second distance greater than the first distance. The second region is free of the dielectric layer.
