- We present a comparative study of copper film growth with a constant energy neutral beam, thermal evaporation, dc magnetron sputtering, high-power impulse magnetron sputtering (HiP-IMS), and bipolar HiPIMS, through molecular dynamics simulations. Experimentally determined energy distribution functions were utilized to model the deposition processes. Our results indicate significant differences in the film quality, growth rate, and substrate erosion between the various physical vapor deposition techniques. Bipolar HiPIMS shows the potential for improved film structure under certain conditions, albeit with increased substrate erosion. Bipolar +180 V HiPIMS with 10% Cu + ions exhibited the best film properties in terms of crystallinity and atomic stress among the PVD processes investigated.
