System for chemical mechanical planarization

Abstract

A semiconductor substrate processing system for polishing a substrate that generally includes a platen and a web of polishing material disposed thereon. Embodiments of the system include a disposable cartridge for housing the web of polishing material, a shield member disposed proximate the web for preventing contamination of the unused portion of the web, a fluid delivery for fixing and freeing the web from the platen, apparatus for controlling the lateral movement of the web, and an apparatus for providing more linear feet of polishing material per height of a roll.
