Abstract
A method of reducing contact size in an integrated circuit includes providing an insulating layer over a semiconductor substrate including a plurality of gate structures, creating an aperture extending through the insulating layer and having side walls, providing a spacer on the side walls of the aperture, and providing a contact in the aperture. The lateral sides of the contact abut the spacer. A contact structure is also disclosed in which a spacer separates a contact from a gate structure to avoid charge gain or loss between the contact and gate structure.
