Abstract
One aspect of the disclosure relates to an integrated circuit structure. The integrated circuit structure may include: a contact line being disposed within a dielectric layer and providing electrical connection to source/drain epitaxial regions surrounding a set of fins, the contact line including: a first portion of the contact line electrically isolated from a second portion of the contact line by a contact line spacer, wherein the first portion and the second portion each include a liner layer and a metal, the liner layer separating the metal from the dielectric layer and the source/drain epitaxial regions, and wherein the metal is directly in contact with the contact line spacer.
