The use of ionized magnetron PVD remedies some of the shortcomings of collimated sputtering. Sidewall coverage, low wafer heating and high deposition rates are some of the advantages gained by I-PVD. Conformal films within trenches and vias are obtainable by increasing ion energy in a controlled manner so as to permit both low energy directional deposition and higher energy resputtering. The two intrinsic advantages of I-PVD are that all depositing ions arrive at normal incidence (instead of just a small fraction) and the arrival energy of the depositing ions is controlled. Improved coverage results.
