ABSTRACTWe have studied the formation of palladium suicide on clean silicon <111> surfaces using in situ spectroscopie ellipsometry. Pd films of thicknesses from 5 to 50 A were studied both as deposited and after annealing to complete the reaction to Pd2Si. The measured dielectric function spectra were analyzed to determine the amounts of Pd2Si and unreacted Pd. Evidence of Pd-Si solid state reaction was detected after all depositions. In the as-deposited films the fraction of suicide increased with the thickness, up to about 40% for the thickest films (50 Å Pd), while the annealed films were completely reacted. These results are consistent with earlier Raman spectroscopy studies.

ABSTRACTMechanical stress and stress evolution in interconnections may cause reliability problems in IC circuits. It is thus of great importance to understand the origin of this stress.In this paper, the stress evolution during the solid state reaction between blanket titanium and aluminum films has been studied by in-situ substrate curvature measurements. Whereas the formation of TiAl3 is expected to induce large tensile stress because of a global volume decrease of 6-8%, curvature measurements of titanium/aluminum dual layers during annealing at 450°C suggests the formation of a compressive compound.The evolution of the average force per unit width of the layer during the solid state reaction is interpreted on the basis of a phenomenological model used to describe stress evolution during silicide formation.
