Popis: Ni silicide and germanosilicide formation with one-step and two-step rapid thermal annealing are compared in this study. The 1st annealing temperature for NiSi and Ni(Si/sub 1-x/Ge/sub x/) in two-step annealing process are investigated with sheet resistance measurements, X-ray diffraction and Auger election spectroscopy. Cross-sectional SEM shows the influence of rapid thennal annealing process on the uniformity of NiSi and Ni(Si/sub 1-x/Ge/sub x/) films. Two-step annealing process was found to improve the uniformity of NiSi and Ni(Si/sub 1-x/Ge/sub x/) films. The results indicate that two-step annealing process would be preferred for NiSi or Ni(Si/sub 1-x/Ge/sub x/) formation on the ultra-shallow junction in the future CMOS technology nodes.
