Polytetrafluoroethylene (PTFE) membrane filters from W. L. Gore & Associates Inc. can be used for liquid filtration applications in microelectronics processing, including  ultrapure water, deionized water, and high purity chemical processing. The filters can achieve higher flow in comparison to other microfiltration technologies, according to the company.

GORE Filters enable semiconductor fabs to realize both improved performance and lower cost of ownership. The drop-in substitution of GORE Filters can upgrade retention performance and reduce particle counts while maintaining desired flow rate, as well as enabling reduced processing times, higher flow rates, and faster bath turnovers.

For processors of high-purity bulk chemicals used in semiconductor fabrication and other microelectronics manufacturing processes, the use of GORE Filters has enabled  improved product quality, increased production capacity, and reduced cost of filtration for high viscosity fluids, acids, bases, solvents, and specialty chemicals.
