W. L. Gore & Associates (Gore) announces a major advancement in filtration technology with the release of GORE® Filters for Semiconductor Applications. This new family of 20 nm- to 100 nm-rated cartridge filters for chemicals, dilute chemicals, and ultrapure water in wet process tools incorporates a new high-flow ePTFE (expanded polytetrafluoroethylene) filtration media that allows a drop-in retention upgrade from 100 nm to 30 nm, enabling cleaner recirculation baths, reduced processing times and significant savings in cost of ownership. The cartridge filters enable up to three times the flow compared to the next best-in-class filters, with improved performance and no sacrifice in retention. GORE® filters provide a drop-in replacement that improves retention performance, reduces particle counts, lowers operating differential pressures, reduces processing times, and enables faster bath turnovers. The filters also allow flow rates to be maintained or even increased with as few as 1/3 the number of filters used previously.
