Abstract:
A method of forming a semiconductor device that includes forming a trench adjacent to a gate structure to expose a contact surface of one of a source region and a drain region. A sacrificial spacer may be formed on a sidewall of the trench and on a sidewall of the gate structure. A metal contact may then be formed in the trench to at least one of the source region and the drain region. The metal contact has a base width that is less than an upper surface width of the metal contact. The sacrificial spacer may be removed, and a substantially conformal dielectric material layer can be formed on sidewalls of the metal contact and the gate structure. Portions of the conformally dielectric material layer contact one another at a pinch off region to form an air gap between the metal contact and the gate structure.

Claim (Index 9):
A method for forming a fin field effect transistor (FinFET) device comprising:\n forming a sacrificial spacer on a sidewall of a gate structure; forming a contact on an opposing sidewall of the gate structure that the sacrificial spacer is present on, the contact in electrical communication with at least one of said source region portion and said drain region portion; removing the sacrificial spacer; and forming a dielectric material layer in the opening exposed by removing the sacrificial spacer, wherein portions of the dielectric material layer contact one another at a pinch off region to form an air gap filling.
