Paper Abstract

Thin film properties of niobium silicide (Si/Nb ~ 2.1) on SiO2/Si substrates after rapid thermal annealing in two different systems were investigated. The structural and compositional properties were examined with X-ray diffraction and Rutherford backscatter-ing spectrometry. X-ray diffraction revealed that NbSi2 was the predominant silicide phase present, as the grain size increased from 10 to 160Å before and after annealing at 1100°C for 10 sec. Isochronal and isothermal annealing at 800-1200°C for 10-120 sec showed that over 50% decrease in resistivity occurred in the first 10 sec and the lowest resistivity value of 85μO-cm was obtained after annealing at 1200°C for 120 sec. Also, a corresponding increase in film reflectance was observed with the decrease in sheet resistivity. Furthermore, annealing at 1300°C led to precipitate formation on the silicide surface.
