A novel salicide process is presented which allows for independent silicidation of source/drain areas and polysilicon gates, thus making it possible to achieve ultra-shallow junction formation with very low gate sheet resistance (Rs) for sub-0.25 μm CMOS device fabrication. Titanium was used to demonstrate this process in a 0.25 μm technology, yielding fully functional transistors with gate Rs<2 Ω/sq
