Schottky Barrier Tuning at NiSi/Si Interface using Pre-silicide Aluminum and Sulfur Co-Implant
In this paper, we examine the physical properties of NiSi/p-Si implanted with various combinations of aluminum (Al) and sulfur (S) doses for Schottky barrier tuning. Techniques used included HRTEM, TOFSIMS, HAADF STEM, and EDX. We also measured the integral interfacial dose (I1D) of Al and S, i.e. amount of Al and S found with 2.5 run of the interface, and correlated it to the Schottky barrier height (SBH). For the split with the same Al and S implant dose, the SBH tuning effect of Al overwhelms that of S and the extracted SBH is 0.137 eV.
