Microporous membranes for microelectronic and semiconductor filtration.

Fluid purity is critical to important fabrication processes such as wet etch and clean, photolithography and chemical mechanical planarization. As these fabrication processes continue to shrink, capturing particles in the nanometer range becomes ever more important. At the same time, contaminant concentrations are rising along with increasingly strict regulations. It’s a situation that requires a multi-stage filtration process—one that 3M microfiltration membranes can help streamline.

In microelectronics, microfiltration membranes remove particles of different class sizes. No matter the application, 3M membranes help filters prevent contamination. They are a critical component of fluid stream filters for semiconductor chip manufacturing, pre-filtering ultra pure water streams and process fluid filtration in LCD TFT manufacturing. No matter the application, expect high-performance filtration when integrating a 3M membrane in your product.
