A method for forming a slot contact structure for n-type transistor performance enhancement. A slot contact opening is formed to expose a contact region, and a barrier plug is disposed within a portion of the slot contact opening in order to induce a tensile stress on an adjacent channel region. The remainder of the slot contact opening is filled with a lower resistivity contact metal. Barrier plug deposition temperature can be varied in order to tune the tensile stress on the adjacent channel region.
