Abstract
A sacrificial layer is formed to cover the gate structures. The sacrificial layer is patterned to form a first opening in the sacrificial layer. A preliminary contact is formed in the first opening and the sacrificial layer is selectively removed. An insulating layer is formed to cover the gate structures and to expose the preliminary contact. The preliminary contact is removed to form a second opening in the insulating layer, and then a contact is formed in the second opening.
