Semitron® CMP LL5 is one of the new materials developed by Quadrant Engineering Plastic Products to deliver longer production life in Chemical Mechanical Planarization retaining rings. Semitron CMP LL5 is an enhanced polyester developed with wear characteristics and inherent quality specifications geared to the semiconductor industry. Laboratory simulations show that Semitron CMP LL5 extends retaining ring-life by as much as 5 times over rings made of traditional PPS, depending on process conditions. The new product is also a lower cost alternative to PPS and suitable for use in all CMP processes, is ideal for use in ring designs that have steel or ceramic reinforcement.
