Fluid purity is essential in semiconductor and microelectronics manufacturing processes such as wet etch and clean, photolithography, and chemical mechanical planarization (CMP). As transistors continue to shrink, it becomes increasingly critical to capture smaller and smaller particles in the nanometer range.
With the unique combination of highest retention and unparalleled flow, GORE Microfiltration Media enable the manufacture of expanded polytetrafluoroethylene (ePTFE) membrane filters used in demanding applications that require repeatable high performance, consistent quality and exceptional product cleanliness.
Gore’s expertise in manufacturing ePTFE and controlling its microstructure allow us to tailor membranes to increase retention, allow greater throughput, or impart specific characteristics needed for the intended use. These capabilities and skills result in filtration for enabling technologies that improve productivity and increase processing yields during microchip fabrication.
Our membrane technology is derived from Gore’s almost four decades of serving the semiconductor and microelectronics markets. We take pride in providing high-quality, high-performance products for the most critical and demanding semiconductor fabrication steps. When our membranes deliver, filter makers can innovate quickly and reliably serve chip makers who produce the microelectronic devices at the center of the digital age.
Technology that Sparks Innovation
Gore’s membranes are designed to help filter makers innovate with confidence in their products’ performance. Available in many pore size ratings, our membranes facilitate the quick development of high-performance filters with high particle capture efficiency and superior flow rates.
ePTFE membrane structures under extreme magnification
The key to our membrane materials’ performance is their microstructure. Gore’s ePTFE-based membranes are comprised of millions of interconnected, continuous fibrils that reliably capture particles in the nanometer range, while allowing high flow rates at a given retention level. The PTFE makeup of our membranes makes them:
- extremely resistant to shedding
- chemically and thermally resistant
- consistent from lot to lot
Other providers of membranes also use ePTFE as a base material. What sets Gore apart is our unparalleled expertise in the manufacture and control of ePTFE’s microstructure to provide the characteristics required in a given application.
The result is high-performing, application-specific membranes that keep pace with the increasingly demanding filtration needs of semiconductor, OLED, LED and hard disk drive processing, as well as high purity process chemical production.
Global Research and Reach
Gore has served the semiconductor and microelectronics markets for over 35 years. In that time, we’ve seen membrane separation processes evolve and transistors shrink to previously unimaginable sizes. Meanwhile, the need for process purity has grown exponentially.
Our expertise in critical applications informs how we serve filter manufacturers — and, in turn, how they serve chip makers. Through R&D and extensive field testing, we have developed a portfolio of membranes that perform as promised to fit the application, each time, every time.
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 membranes to meet the tight timelines expected in this always innovating industry.
GORE Microfiltration Media are available as membrane rolls in a range of sizes and capabilities to fit various critical applications and microfiltration device formats.
Pore size ratings: Our microfiltration media are offered in a range of membrane filter pore sizes, from 30 nm (0.03μm) to 10μm.
Pre-filter and final filter: With various pore size ratings, our membranes support both pre-filter (1.0–10.0 μm) and leading-edge final filter (30 nm–200 nm) applications.
Flow rates: Our membranes are engineered to enable various flow rates as required by each application.
Hydrophilic and hydrophobic: Our membranes are available as either hydrophilic media, used in water-based processes; or hydrophobic media, typically used in aggressive chemical and solvent-based applications. Both types are highly uniform and best in class.
Laminated media: Typical membranes come standard as a layer of ePTFE without backing. Upon request, we also offer hydrophobic membranes as a laminate of ePTFE bonded to a non-woven backing material for added support and strength.
Discs: In addition to membrane rolls used in cartridge filters, we provide membrane discs in custom sizes for varied applications.
