Q&A: Flow and Liquid Analysis advancements in semiconductor manufacturing

Flow and liquid analysis play a vital role in semiconductor manufacturing, where ultra-pure water and precise chemical control are essential for producing defect-free chips. Accurate measurement technologies help maintain process integrity, ensure compliance with stringent purity standards and reduce downtime. This Q&A highlights common challenges and solutions for achieving reliable flow and liquid analysis in these demanding environments. 

Q: What challenges exist for flow measurement in ultra-pure water applications? 

A: Ultra-pure water has extremely low conductivity, making traditional electromagnetic flow meters ineffective. Space constraints and ease of installation also pose challenges, especially in retrofit or skid-based systems. 

Q: Which flow technologies address these challenges? 

A: Inline and clamp-on ultrasonic flowmeters, such as Endress+Hauser’s Proline Prosonic Flow W 400 and P 500, work without conductivity and allow non-invasive installation. Coriolis flowmeters, like Proline Promass K 10, offer high accuracy and require no straight pipe runs, making them ideal for tight spaces. 

Q: Why measure Total Organic Carbon (TOC) in semiconductor manufacturing? 

A: TOC monitoring ensures water quality by detecting organic contaminants that could damage chip surfaces. Ultra-low TOC analyzers help maintain stringent purity standards and prevent costly defects. 

Q: How does Heartbeat Technology improve reliability? 
A: Heartbeat Technology provides in-situ device verification, diagnostics and predictive maintenance without process interruption. This reduces downtime and supports ISO-compliant quality assurance.
