Abstract (in Japanese) (See Japanese page) 
(in English) Impurity (Sb, P, B or As)-implanted Ni-silicides formed on thermally-grown SiO2 were characterized by Raman scattering spectroscopy and X-ray photoelectron spectroscopy (XPS), where the Ni-silicide/SiO2 interfaces were analyzed through SiO2 for the samples after removing the Si substrate from the backside in addition to the analysis from the surface side to evaluate the correlation between the effective work function and chemical composition or impurity concentration at the interface. Raman scattering spectra measured from the Ni-silicide surface sides show that mono-silicide phase are dominant but partly Si-rich and N-rich phases coexist. On the other hand, in Raman spectra of Ni-silicides measured from the back side through SiO2 layer, no signals due to Ni-rich phase was detectable but the signals due to mostly mono-silicide phase and slightly Si-rich phase was observed. The formation of a Si-rich region at and near the Ni-silicides/SiO2 interface was also confirmed by XPS measurements from the back side. In the case with P-, Sb-, and As-implanted samples, the impurities piled up at the Ni-silicide/SiO2 interface but no oxide component of the impurities was detected. In contrast, for B-implanted case, no pile-up of B atoms but the BOx component was observed at the interface. For P- and Sb-implanted Ni-silicides, the difference in effective work function between the Ni-silicide surface and the Ni-silicide/SiO2 interface can be interpreted mainly in terms of the difference in the Ni composition since a similar change in the work function was also observed in pure Ni-silicide case. On the other hand, for the B-implanted Ni-silicide, it is suggested that the effective work function lowering with the decrease in the Ni composition is suppressed remarkably.
