Abstract
Specific contact resistivities of the Al/TiW/TiSi2 /Si system are characterized. It is found that without a TiW barrier layer, Al can penetrate through the TiSi2 layer and significantly affect the TiSi2 /Si interfacial contact resistance. Intrinsic TiSi2 contact resistivities to n+and p+silicon are characterized with a TiW barrier between the silicide and the aluminum. TiSi2 contact resistivity to n+silicon is found to be about one order of magnitude lower than that of Al to n+silicon. However, TiSi2 to p+silicon contact resistivity is higher than that of Al to p+silicon and is very sensitive to the boron implant dose.
