Cabot Microelectronics Corporation Launches Three New CMP Polishing Pads From Its Epic(R) D100 Platform

AURORA, Ill., Oct 20, 2010 (GlobeNewswire via COMTEX) --

Cabot Microelectronics Corporation (Nasdaq:CCMP), the world's leading supplier of chemical mechanical planarization (CMP) polishing slurries and growing CMP pad supplier to the semiconductor industry, today announced the launch of three new CMP polishing pads from its Epic(R) D100 platform that are intended to address customers' specific needs by polishing application.

The Epic(R) CMP polishing pads are the result of extensive research and development by Cabot Microelectronics to deliver best-in-class performance and quality at advanced technology nodes, and optimal cost of ownership. Cabot Microelectronics identified and developed a key thermoplastic technology allowing for continuous manufacturing of CMP pads. This continuous manufacturing process has attracted many customers due to its unique design that successfully reduces pad-to-pad variation. At the elevated temperatures encountered in the CMP process, thermoplastic polyurethane polymers are softer than conventional thermoset polymers. This characteristic of thermoplastic polyurethane polymers has a direct impact on customers' polishing performance as it helps improve defectivity by minimizing microscratches on customers' wafers.

Advances in semiconductor IC technology have resulted in a complex set of requirements for CMP processes that differ by IC manufacturer and IC product. As a result, Cabot Microelectronics has expanded its Epic(R) product portfolio to now include the following new CMP polishing pads:

  --  Epic(R) D110-CU, with an engineered surface finish optimized for the
      advanced copper CMP application, provides extremely short break-in time
      (i.e., the time needed to reach steady state performance) and excellent
      defectivity performance. A major customer confirmed the improvement in
      break-in time, while still benefiting from the improvement in
      defectivity of the Epic(R) platform.
  --  Epic(R) D120-STI has an engineered surface finish optimized for the
      advanced shallow trench isolation (STI) CMP application. This CMP
      polishing pad provides short break-in time and enhanced defectivity
      performance when used with ceria CMP slurries. A customer reported
      significant improvement in defectivity for its STI process when using
      the D120-STI pad.
  --  Epic(R) D150-W, with stronger top sheet/sub-pad adhesion, provides
      extremely long pad life and enhanced defectivity performance for
      tungsten CMP applications. Customers have validated three times longer
      pad life compared to conventional pads.


Dinesh Khanna, Cabot Microelectronics' Global Business Director for CMP Pads, stated, "We have expanded the Epic(R) product portfolio to respond to specific customer needs and to deliver best-in-class performance for a range of CMP polishing applications. We believe our new pad products offer customers unmatched quality, performance and optimal cost of ownership."
