Application Overview
In semiconductor manufacturing, wet processes impose extremely high requirements on the safety, purity, and stability of chemical fluid transfer. Fluoroplastic magnetic pumps, featuring a seal-less design, excellent corrosion resistance, and zero-leakage performance, are widely used in wafer cleaning, etching, chemical mechanical polishing (CMP), as well as waste chemical recovery and treatment systems.
The semiconductor industry relies on high-purity, highly corrosive chemicals such as strong acids, alkalis, and organic solvents, which place stringent demands on material compatibility and operational reliability. By utilizing magnetic drive technology for non-contact power transmission, fluoroplastic magnetic pumps completely eliminate leakage risks, effectively ensuring production safety, environmental compliance, and high product yield. They have become a critical fluid-handling solution in semiconductor wet process applications.
Typical Applications
High-Purity Chemical Transfer
Safely transports high-purity corrosive chemicals such as HF, H₂SO₄, HCl, HNO₃, and NH₄OH, minimizing the risk of contamination and leakage.
Wafer Cleaning and Wet Process Operations
Used in RCA cleaning systems, wet benches, and chemical circulation loops to ensure stable process conditions and consistent cleaning performance.
Etching and Surface Treatment Processes
Provides continuous and stable delivery of etching solutions, improving process repeatability and surface treatment uniformity.
CMP Auxiliary Systems
Suitable for the transfer of slurries and chemical additives, supporting high-cleanliness requirements and stable CMP process control.
Why choose fluoroplastic magnetic pumps for applications in the semiconductor industry?
Zero-Leakage Design for Ultra-High Safety
The magnetic drive structure eliminates mechanical seals, completely preventing leakage of hazardous and high-purity chemicals while ensuring cleanroom safety and process reliability.
Outstanding Corrosion Resistance and Chemical Compatibility
Fluoroplastic-lined wetted parts (PTFE / FEP / PFA) offer excellent resistance to strong acids, alkalis, and solvents commonly used in semiconductor wet processes.
High-Purity Fluid Handling with Minimal Contamination Risk
A non-metallic flow path reduces the risk of ion contamination, meeting the stringent purity requirements of wafer cleaning, etching, and chemical delivery systems.
Stable and Reliable Operation for Continuous Production
Designed for long-term, stable operation under harsh chemical conditions, these pumps reduce unplanned downtime and support 24/7 semiconductor manufacturing.
Easy Integration with Automated Systems
Compatible with automated chemical delivery systems (CDS) and centralized chemical supply lines, enabling precise process control and smart factory implementation.
Low Maintenance and Reduced Total Cost of Ownership
The seal-less design minimizes wear parts and maintenance frequency, lowering operating costs while improving overall equipment availability.
Supports Environmental Protection and Regulatory Compliance
By preventing chemical leakage and vapor emissions, fluoroplastic magnetic pumps help semiconductor fabs meet strict environmental, safety, and regulatory standards.
