Semitron® Family of Products
The Semitron® Semiconductor Grade thermoplastic products were developed to help designers and users optimize the performance of semiconductor and electronics device manufacturing equipment. In addition to device manufacture, many of these materials are ideal for specific environments where wear-resistance, chemical-resistance and the management of static electricity are required. Two groups of Semitron® products have been developed. One, well suited for device handling and test applications, and a second for next-generation CMP use. Semitron® grades are available in sheet, rod (some formulations) and machined parts. Some are engineered with specific ESd properties while others offer enhanced purity, wear properties and higher performance in various semiconductor applications.
