Optimizing Ultrapure Water (UPW) Quality in Smelting & Refining: Why Particle Counting Matters
In today’s semiconductor manufacturing environment, maintaining the highest standards of ultrapure water (UPW) quality is more critical than ever—especially in high-temperature, high-precision operations like smelting and refining. Even submicron particles can lead to yield loss, equipment degradation, or downstream contamination.
At Particle Measuring Systems (PMS), we understand the unique particle challenges that arise in these demanding environments. Our latest white paper, “Smelting and Refining: UPW and the Application of Particle Counters,” explores how UPW systems used in smelting and refining processes benefit from continuous particle monitoring and how it supports defect reduction and process control.
Why Particle Monitoring in Smelting and Refining?
Smelting and refining processes are intense and often involve the use of aggressive chemicals and high temperatures. These factors can compromise materials and release particles into UPW streams, risking contamination in critical semiconductor steps such as etching, polishing, and deposition. This technical paper explains how:
-
Specific UPW distribution points in smelting and refining can become contamination sources.
-
Real-time particle counters provide actionable insight that helps identify and localize particle events.
-
High-sensitivity liquid particle counters allow manufacturers to fine-tune filtration and purification strategies, directly improving yield and reliability.
Real-World Use Cases
You’ll also find practical guidance and data from actual manufacturing environments. Learn how fabs are using particle monitoring to:
-
Isolate problematic tools and materials,
-
Maintain consistent UPW quality,
-
Reduce chemical and filtration costs through smarter monitoring,
-
And ultimately protect wafers from particle-induced defects.
