Abstract A Monte-Carlo comupter simulation has been performed to describe, atatomic level, the growth of TiN films formed by ion beam enhanced deposition(IBED). The simulation is based on a random target, fixed free path of moving par-ticles and binary collisions. An alternate process of deposition of titanium atomsand implantation of nitrogen ions is applied instead of the actual continuous andsynchronous process of IBED. According to the actual conditions, the adsorptionof nitrogen gas, which is leaked out from the ion source, at the fresh titaniumlayer surface has been considered. In addition, the change of the composition pro-file and the density profile during film growth is taken into account. It shows thatthe titanium deposition rate has strong influence on the film composition. Whenthe titanium deposition rate is low, the nitrogen concentration of the film is rela-tively insensitive to the atomic arrival ratio, R, of implanted nitrogen ions to de-posited titanium atoms. It is demonstrated that the width of the intermixed regionbetween the film and substrate increases with the increase of R. The results obtain-ed are in agreement with the experimental measurements.
