Interface properties and effective work function of Sb‐predoped fully silicided NiSi gate

We employ first principles calculations to understand the surface termination dependent structural and magnetic properties of (0001) SmCo5 surface slabs. For our study, three different sub‐layer terminated surface slabs, namely Co3–(SmCo2–Co3)n, SmCo2–(Co3–SmCo2)n, and (Co3–SmCo2)n with thicknesses varying from n = 1 to n = 10, are considered. Our results revealed that the Co3 sub‐layer terminated surface slab (first case) has higher structural stability, spin polarization, and work function when compared to the other two cases and such terminated surface slabs can be potentially used for fabricating exchange‐coupled magnets.

Work function shifts for fully silicided (FUSI) Pd2Si gates with BF2 and P predoping, originally observed as the flatband voltage shifts in metal-oxide-semiconductor (MOS) diodes, were also reproducible for backside x-ray photoelectron spectroscopy measurements. The Pd composition ratios of FUSI layers were reduced in the vicinity of the gate SiO2 layer, which directly affects apparent work function in the MOS system. However, other non-negligible changes, such as pileup of predoped elements and Pd precipitation, were also found for the predoped cases. The work function shift by predoping should be considered to be a result of interaction of such multiple factors.
