  • Patent number: 11973117
    Abstract: Methods of forming contacts for source/drain regions and a contact plug for a gate stack of a finFET device are disclosed herein. Methods include etching a contact opening through a dielectric layer to expose surfaces of a first source/drain contact and repairing silicon oxide structures along sidewall surfaces of the contact opening and along planar surfaces of the dielectric layer to prevent selective loss defects from occurring during a subsequent selective deposition of conductive fill materials and during subsequent etching of other contact openings. The methods further include performing a selective bottom-up deposition of conductive fill material to form a second source/drain contact. According to some of the methods, once the second source/drain contact has been formed, the contact plug may be formed over the gate stack.
