In this research, the Y2O3 layer is doped with the zirconium through co-sputtering and rapid thermal annealing (RTA) at 550°C, 700°C, and 850°C. Then the Al electrode is deposited to generate two kinds of structures, Al/ZrN/ Y2O3/ Y2O3+Zr/p-Si and Al/ZrN/ Y2O3+Zr/ Y2O3/p-Si. According to the XRD results, when Zr was doped on the upper layer, the crystallization phenomenon was more significant than Zr was at the bottom layer, meaning that Zr may influence the diffusion of the oxygen. The AFM also shows that the surface roughness of Zr has worse performance. For the electrical property, the influence to overall leakage current is increased because the equivalent oxide thickness (EOT) is thinner.

AbstractWe comparatively studied the formation of ultra thin Co silicides, Co2Si, CoSi and CoSi2, with/without a Ti-capped and Ti-mediated layer by using rapid thermal annealing in a N2 ambient. Four-point-probe sheet resistance measurements and plan-view electron diffraction were used to characterize the silicides as well as the epitaxial characteristics of CoSi2 with Si. We found that the formation of the Co silicides and their existing duration are strongly influenced by the presence of a Ti-capped and Ti-mediated layer. A Ti-capped layer promotes significantly CoSi formation but suppresses Co2Si, and delays CoSi2, which advantageously increases the silicidation-processing window. A Ti-mediated layer acting as a diffusion barrier to the supply of Co suppresses the formation of both Co2Si and CoSi but energetically favors directly forming CoSi2. Plan-view electron diffraction studies indicated that both a Ti-capped and Ti-mediated layer could be used to form ultra thin epitaxial CoSi2 silicide.
