<p>A polishing pad resistant to delamination The present invention provides, chemical mechanical polishing pad (100) with improved polishing properties and longevity for polishing semiconductor wafers (195). The polishing pad comprises a thermoplastic backing film (105) and a pressure sensitive adhesive (110) coupled to the thermoplastic backing film. The pressure sensitive adhesive is configured to couple a chemical mechanical polishing pad to a polishing platen (115). The pressure sensitive adhesive is further configured to provide an interface capable of substantially preventing delamination of the polishing pad from the polishing platen for at least about 4 days exposure to a polishing slurry medium having a pH of about 4 or higher.
