Fluid purity is essential in semiconductor fab and microelectronics manufacturing and processing, like wet etch and clean (WEC), photolithography and chemical mechanical polishing (CMP). As transistors continue to shrink to unimaginable sizes, it becomes increasingly critical to capture the tiniest particles in the nanometer range for effective micro-contamination control.

With a unique combination of the highest retention and unparalleled flow, GORE Microfiltration Media enable the manufacture of expanded polytetrafluoroethylene (ePTFE) membrane filters to improve productivity and increase processing yields.

For applications where reliability is critical, we give filter makers what they expect from a membrane supplier without compromises to retention and flow or quality. Our high retention and flow rate membrane assures repeatable high performance, consistent quality and exceptional high cleanliness.


Our unparalleled expertise in manufacturing ePTFE and controlling its microstructure allow us to tailor membranes to increase retention and enable greater throughput or impart specific characteristics required for their intended use.

Gore is more than a membrane company — we’re a global expert in filtration. For over four decades, we’ve delivered air, gas, liquid and particle filtration solutions to help our partners purify processes, increase yields and control costs.

We continue to set the industry standard in the liquid filtration market for membranes that bring high-quality, high-performance and reliability in the most critical semiconductor and microelectronics fabrication steps. And as chip design gets finer, we continue to develop new membranes so filter manufacturers can keep up with industry needs and challenges to improve process yields.

Product Offerings

Through R&D and extensive field testing, we’ve developed a portfolio of GORE Microfiltration Media designed to fit many critical applications and microfiltration device design formats. Available as rolls in a wide microfiltration pore size range, our membranes facilitate the rapid development of high-performance filters with high particle efficacy and high flow rates. We also offer membrane discs in custom sizes for diverse applications.

With Gore’s global manufacturing and supply chain, we can easily communicate our expertise to manufacturers in Asia, the Americas and all points between, delivering ePTFE membranes to meet the tight timelines expected in this always innovating industry.

Materials Construction Pore Reference Size (μm) Capabilities / Intended Use
