  • Abstract
    An extremely low contact resistivity of 6-7 × 10-9 Ω·cm2 between Ni0.9Pt0.1Si and heavily doped Si is achieved through Schottky barrier engineering by dopant segregation. In this scheme, the implantation of B or As is performed into silicide followed by a low-temperature drive-in anneal. Reduction of effective Schottky barrier height is manifested in the elimination of nonlinearities in IV characteristics.
