Abstract

Chemical mechanical polishing (CMP) technology has been widely used for global planarization of multi-level interconnection for ULSI applications. However, the cost of ownership and cost of consumables are relatively high because of expensive slurry. In this paper, so as to investigate the influence of mixed abrasive slurry (MAS), such as $ZrO_2$, $CeO_2$, and $MnO_2$ for Ti-CMP application.
