Abstract
A method, apparatus, and manufacturing system are disclosed for a fin field effect transistor having a reduced risk of short circuits between a gate and a source/drain contact. In one embodiment, we disclose a semiconductor device including a fin structure comprising a fin body, source/drain regions, and a metal formation disposed above the source/drain regions, wherein the metal formation has a first height; and a gate structure between the source/drain regions, wherein each gate structure comprises spacers in contact with the metal formation, wherein the spacers have a second height less than the first height, a metal plug between the spacers and below the second height, and a T-shaped cap above the metal plug and having the first height.
