Article Description

The suitability of focused ion beam (FIB) deposited metals, specifically platinum and tungsten, for use in making a direct contact to bare silicon was experimentally studied. The average contact resistance of FIB-deposited platinum contacts to silicon was on the order of 10ωcm, while FIB-deposited tungsten contacts were on the order of 10ωcm, though individual contacts varied widely in their resistance. This difference was attributed to silicide formation at the metal-silicon junction for the platinum contacts.
