Abstract

TiN is one of the mostly used barrier materials in copper metallization because of low friction coefficient and superior electrical properties. We need to investigate for the etching characteristic of TiN. In this study, we investigated about etching characteristic of TiN using $BCl_3$/Ar inductively coupled plasma system. The etch rate was measured by a depth pro filer. The chemical etching reactions of the TiN surface was investigated X-ray photoelectron spectroscopy.
