The method further includes forming at least one plug on top of the layer of metal material such that the at least one plug is integrally formed with the layer of scaffolding material. The method further includes removing the layer of hardmask material such that a top surface of the layer of metal material is exposed except where the at least one plug is formed on top of the layer of metal material. The method further includes recessing the layer of metal material where the top surface of the layer of metal material is exposed. The method further includes removing the scaffolding material.
