AbstractLow resistivity TiSi2, CoSi2 and NiSi are the three primary candidates for metal contacts in sub-0.25 μ m devices. In the present paper, we review recent progress in the investigations of lowresistivity contacts, which include enhanced formation of C54-TiSi2 on (001)Si by tensile stress, high temperature sputtering, and interposing Mo or TiN layer, improved thermal stability of C54-TiSi2 by the addition of N2 during Ti sputtering or N implantation in (001)Si, self-aligned formation of CoSi2 on the selective epitaxial growth silicon layer on (001)Si, effects of stress on the epitaxial growth of CoSi2 on (001 )Si, improvement of thermal stability of CoSi2 by nitrogen ion implantation or high temperature sputtering, and improvement of thermal stability of NiSi by nitrogen ion implantation or compressive stress.

AbstractMolybdenum nitride thin films were prepared by N2+ implantation with acceleration energy of 20 keV and the ion dose of 3×1017 ions/cm2. The structural property and thermal stability of the films were investigated by XRD, AES, AFM and RBS. The crystal structure of N2+ implanted molybdenum thin films (Mo-N2+) which had microcrystalline state was transformed to γ-Mo2N phase with a preferred (111) orientation after a post-annealing at 500 °C for 30min. However, a silicide reaction was not observed even after the annealing at 700 °C, which is due to the modification of the interface between Mo thin film and Si substrate by N2+ implantation. Also, Cu diffusion did not seem to be induced by the annealing at 700 °C for 30 min. The internal stress of the Mo-N2+ thin films during post-annealing at 600 °C for 30min was found to change from highly compressive stress to low tensile stress.
