Abstract :
Highly thermal robust Ni-germanosilicide has been developed using the novel NiPt/Co/TiN tri-layer. Ni-germanosilicide properties were characterized with different source/drain dopants and Ge concentrations for nanoscale CMOSFETs application. The sheet resistance was degraded as the Ge concentration increases in Si1-xGex. Low temperature silicidation and wide range of RTP process window are achieved as well as the improvement of the thermal stability according to different dopant types by the subsequent Co and TiN capping layer above NiPt on Si1-xGex.
