Embodiments of the present invention provide improved methods of contact formation. A self aligned contact scheme with reduced lithography requirements is disclosed. This reduces the risk of shorts between source/drains and gates, while providing improved circuit density. Cavities are formed adjacent to the gates, and a fill metal is deposited in the cavities to form contact strips. A patterning mask is then used to form smaller contacts by performing a partial metal recess of the contact strips. |
