Ion irradiation and thermal treatment leads to strong changes in the p
hysical and chemical properties of photoresist materials. Among others
modifications it is observed by Rutherford Backscattering that molecu
les containing sulfur, that is inhibitor molecules and their fragments
, tend to segregate close to the surface region. This behavior can be
explained by assuming a model where the diffusion process of these mol
ecules is followed by: (a) trapping at radiation-induced defects in th
e near surface region and (b) chemical reaction with the implanted ion
and/or indiffusing oxygen. (C) 1997 Elsevier Science B.V.
