Methods for forming a semiconductor structure and semiconductor structures are described. The method comprises patterning a substrate to form a first opening and a second opening, the substrate comprising an n transistor and a p transistor, the first opening over the n transistor and the second opening over the p transistor. The substrate may be pre-cleaned. A ruthenium silicide (RuSi) layer is selectively deposited on the p transistor. A titanium silicide (TiSi) layer is formed on the n transistor and the p transistor. An optional barrier layer may be formed on the titanium silicide (TiSi) layer. The method may be performed in a processing chamber without breaking vacuum.
