Lateral Distribution

Abstract

An analytical model with lateral straggling parameters was developed to describe the tilt dependence of ion-implantation profiles. There are three parameters associated with depth-dependent lateral straggling into the model. On the basis of comparison between experimental and analytical data, a database of ion-implantation profiles that includes lateral-straggling parameters have established. The data with tilt 0° were evaluated using off angle substrates.
