Filtration in Electronics & Semiconductor Fabrication

Optimizing filter performance throughout your operation to remove contaminants and ensure high yields.

Semiconductor Fabrication

Our broad range of membrane and depth media provides contamination control in liquids and gases and are suitable for point-of-use to bulk distribution.


CMP Slurries

Filtration in slurry mixing and distribution systems typically use multiple cartridge filters to remove particulates and assure proper performance of polishing tools. Filters protect the polishing process by removing debris from a recirculated solution.


Ultrapure Chemicals

Assuring contaminant free chemicals in bulk and point-of-use locations is critical in the electronics process. Our selection of depth filters to high purity membranes optimize yields. Membrane filters prevent defects by removing particulate and agglomerates to the 0.02-micron level.


Process Gases

Contamination control for gases can improve yields by removing particulates that cause defects in wafers or substrates. Gas distribution and point-of-use systems are all designed to maintain purity. Proper filtration will insure against system upsets and contamination. 


Ultrapure Water

Critical Process Filtration offers products that are used throughout the production of Ultrapure water, from particle reduction of incoming water through maintaining of ultrapure water in recirculation systems.


Filtration of photoresists, developers, coatings and solvents provides high quality control by removing contaminants from large volumes of chemicals. The final filters optimize photolithography yields by removing particulates and preventing microbubble formation.


Flat Panel Displays

As the demand for high resolutions increases, so does the need for cost-effective contamination control, including filtration of process fluids. We offer a broad selection of filtration media for photoresists, etchants, strippers and the ultrapure water used to mix solutions and rinse the displays.


Data Storage

Filter solutions for CMP slurries, ultrapure water, substrate cleaning and preparation, media cleaning and chemicals used in plating and coating operations.



Our polypropylene depth solutions are suitable for plating and printed circuit boards. Activated carbon filters remove organic contaminants and chlorine from plating baths. Plating, etching and cleaning baths are often recirculated through filters to maintain purity.

Quality Assurance and Standards

Critical Process Filtration filters are designed for use in cGMP compliant processes. Our state-of-the-art manufacturing facility and quality-management system both meet ISO 9001:2015 standards. Each operation from assembly and test to cleaning, drying, and packaging is done in appropriately rated clean rooms, and each filter is assigned a lot code to ensure the traceability of manufacturing data and materials. A sophisticated MRP system collects and processes real-time data from manufacturing centers and inspection points.
