SemitronÂ® CMP XL20 is a modified polyamide-imide. It consistently outlasts all other engineering plastics in all major process environments and up to 20 times longer than PPS rings. Semitron CMP XL20 has the optimum combination of long life in use and mechanical properties needed in demanding process environments. Semitron CMP XL20 is the magic bullet for very demanding applications. It is the next generation standard, and it is available today.
Semitron CMP XL20 sports the best combination of wear life and mechanical strength of any plastic tested in recent CMP simulation studies.
Chemical-mechanical planarization (CMP) is a highly accurate polishing process that flattens and smooths silicon wafer surfaces. The process creates a more uniform platform on which to build ultrafine, multilayer integrated circuitry. The more widespread use of CMP is posing challenges for semiconductor manufacturing consumables.
Semitron XL-20 is the logical choice for replacement of current 200mm & 300mm PPS Retaining Rings. Due to resin supply constaints on Techtron PPS, Quadrant is currently phasing out production of Techtron tubes for the 200mm retaining rings & customers worldwide are finding Semitron XL-20 as the most economical choice due to cost savings associated with longer part life. See the attachments to the left of this page for additonal information.
