The influence of irradiation of Al or Al-based films on the surface mo
rphology is studied by a number of methods. F, B, Mg, Cd, As, Sb, Ct a
nd Ar were chosen as implanting species in order to cover a wide varie
ty of chemical reactivities with aluminium. Implantation of boron and,
to a lesser extent, of fluorine or chromium was found beneficial in s
uppressing population of hillocks, predominantly those of medium or la
rger size.
