Electronics & Semiconductor Manufacturing Filtration

Process Overview

Semiconductor and electronics manufacturing processes demand strict control of particulate contamination and chemical purity.
From wafer fabrication to precision cleaning and chemical delivery systems, filtration is essential to ensure product quality and process consistency.

Even sub-micron particles can cause circuit defects, yield loss, or equipment damage.
Filtration systems must therefore provide stable, high-precision performance without introducing additional contamination.

Key Filtration Applications

Ultra-Pure Water (UPW) Filtration
• Final-stage filtration for wafer cleaning and rinsing processes
• Removal of sub-micron particles to maintain ultra-low contamination levels
• Protection of high-purity water distribution systems

Chemical Filtration (Wet Process & Etching)
• Filtration of acids, solvents, and process chemicals
• Removal of particles that can cause wafer defects or surface irregularities
• Stable performance in chemically aggressive environments

Slurry Filtration (CMP Process)
• Removal of oversized particles and agglomerates in polishing slurries
• Ensuring uniform polishing and surface finish quality
• Prevention of scratch defects on wafer surfaces

Gas Filtration & Process Protection
• Filtration of process gases and compressed air systems
• Removal of particulate contamination in gas delivery lines
• Protection of sensitive process equipment and chambers

Filtration Challenges

Electronics and semiconductor processes require extremely low contamination levels and high material compatibility.
Conventional filter media may introduce fiber shedding, extractables, or unstable filtration performance, which can negatively impact yield and product quality.

CMI Filtration Solutions

CMI sintered metal filters provide a stable and contamination-free filtration solution, ensuring precise particle retention without media migration.
These filters are suitable for high-purity applications requiring consistent performance and long operational life.
