抄録(英) The characteristics of Ni-Germanosilicide were studied by sheet resistance, Field Emission Scanning Electron Microscope (FE-SEM), X-Ray Diffraction (XRD) and X-ray Photoelectron Spectroscopy (XPS). It was found that Ni-Germanosilicide formed using pure-Ni has a very poor thermal stability. After the post-silicidation annealing, severe agglomeration and Ge segregation were occurred and almost all the silicide layer was replaced by oxide and remained Ge compound. That is, there happened abnormal oxidation of Ni-Germanosilicide. To prevent the unintended oxidation or to improve the Ni-Germanosilicide thermal stability, various kinds of triple-layer metal structures were applied in this work and Ti/Ni/TiN triple-layer was found to be very effective structure to prevent the unwanted abnormal oxidation and hence to improve the thermal stability of the Ni-Germanosilicide.
