Durability and/or longevity of a diamond-like carbon (DLC) layer can be improved by varying the voltage and/or ion energy used to ion beam deposit the DLC layer. For example, a relatively low voltage may be used to ion beam deposit a first portion of the DLC layer on the substrate, and thereafter a second higher voltage(s) used to ion beam deposit a second higher density portion of the DLC layer over the first portion of the DLC layer. In such a manner, ion mixing at the bottom of the DLC layer can be reached, and the longevity and/or durability of the DLC improved.

An air ion collimator is added to ionizers with integrated fans that are used to remove static charge. Three mechanisms minimize air ion losses through recombination. Hence, the collimator increases the air ions that are available for charge removal. First, reducing turbulence slows air ion mixing. Second, air entrainment into fast moving air ion zones further slows the rate of air ion losses by dilution. The rate of recombination reaction slows with decreasing ion density. Third, vanes within the collimator delay mixing. In addition to conserving air ions, the collimator directs more ions to the target. Air ions lost to grounding are reduced. Again, more air ions are available to remove static charge from the target.
