How to Select Peristaltic Pump Tubing for Semiconductor Etching Chemicals
Why CJan PTC Peristaltic Pump Tubing Is a Reliable Choice for Corrosive Chemical Transfer
Introduction
In semiconductor manufacturing, chemical delivery systems play a critical role in ensuring process stability, product quality, and equipment reliability. Among these systems, peristaltic pumps are widely used for dosing and transferring etching chemicals because the pumped fluid only contacts the tubing, minimizing contamination and simplifying maintenance.
However, selecting the right peristaltic pump tubing is essential. The tubing must withstand aggressive chemicals while maintaining flexibility, dimensional stability, and long service life.
Recently, a semiconductor equipment manufacturer approached CJan Fluid Technology Co., Ltd. for a tubing solution capable of transferring various semiconductor etching chemicals. After evaluating the application conditions, our engineering team recommended the PTC Chemical Resistant Peristaltic Pump Tubing, which successfully met the customer's performance requirements.
Customer Application
The customer specializes in manufacturing semiconductor process equipment used for chemical etching applications.
The peristaltic pump tubing is primarily used for transferring semiconductor etching chemicals at room temperature.
Typical chemicals include:
Glass Etchant
Hydrofluoric Acid (HF)
Water (H₂O)
Ammonium Fluoride (NH₄F)
Silicon Etchant
Hydrofluoric Acid (HF)
Nitric Acid (HNO₃)
Acetic Acid (CH₃COOH)
Water (H₂O)
Aluminum Etchant
Phosphoric Acid (H₃PO₄)
Nitric Acid (HNO₃)
Acetic Acid (CH₃COOH)
Water
The overall chemical concentration is below 20%, and the tubing is primarily used for laboratory validation, chemical dosing, and etching process verification.
Engineering Challenges
Although the operating temperature is ambient, semiconductor etching chemicals present significant challenges for tubing materials.
The tubing must provide:
Excellent chemical resistance to mixed acids
Stable pumping performance
Long flex life under repeated compression
Low contamination risk
Consistent flow accuracy
Easy replacement during maintenance
Because peristaltic pumps repeatedly compress the tubing during operation, ordinary plastic tubing often hardens, cracks, or loses elasticity after prolonged exposure to corrosive chemicals.
Recommended Solution: CJan PTC Chemical Resistant Peristaltic Pump Tubing
After reviewing the chemical compatibility and operating conditions, CJan Fluid Technology Co., Ltd. recommended the PTC Chemical Resistant Peristaltic Pump Tubing.
The PTC series is specifically designed for aggressive chemical transfer applications where both chemical resistance and pumping durability are required.
Why PTC Is Suitable for Semiconductor Etching Chemicals
Excellent Chemical Resistance
PTC tubing demonstrates excellent compatibility with many commonly used semiconductor chemicals, including:
Hydrofluoric Acid (HF)
Nitric Acid (HNO₃)
Phosphoric Acid (H₃PO₄)
Acetic Acid (CH₃COOH)
