A device including oxide spacer in a contact over active gates (COAG) and method of production thereof. Embodiments include first gate structures over a fin of a substrate and second gate structures, each over an outer portion of the fin and a shallow trench isolation (STI) layer adjacent to the fin; a first raised source/drain (RSD) in a portion of the fin between the first gate structures and a second RSD in the portion of the fin between the first and second gate structures; a metal liner over the first and second RSD and on sidewall portions of the first and second gate structures; a metal layer over the metal liner; and an interlayer dielectric (ILD) over the metal liner and portions of the first and second gate structures.
