Semiconductor Manufacturing

As semiconductor processes move toward smaller feature sizes, higher cleanliness, and tighter contamination control, small components such as fasteners, standoffs, bushings, and seals can have a direct impact on process stability and equipment reliability. In wet-process, vacuum, high-temperature, and precision inspection environments, unsuitable materials may increase the risk of metal-ion contamination, particle generation, outgassing, corrosion, or static-related issues, which can affect equipment uptime and process yield.
For applications requiring chemical resistance, low contamination, electrical insulation, low outgassing, or dimensional stability, selected high-performance engineering plastics can be used where their properties fit the actual process conditions. Link-Upon has built extensive experience in engineering plastic applications and manufacturing, evaluating material properties together with component design and manufacturability. We help customers select suitable materials and component solutions for different process environments, from prototype development through stable production.

Industrial Applications

Engineering plastic parts are used in semiconductor manufacturing, wafer handling, packaging/test systems, and automation. With suitable grades, design, and process control, they can support chemical resistance, low metal contamination, insulation, static control, low outgassing, wear resistance, and dimensional stability.

Wet Processing & Etching Equipment: Chemical Resistance and Contamination Control

Wafer cleaning and wet etching use acids, alkalis, and other process chemicals at different concentrations and temperatures, including solutions containing hydrofluoric acid or sulfuric acid.
If metals or plastics are not compatible with the process medium, corrosion, leaching, or material degradation can occur.
Fluoropolymers such as PTFE, PFA, and PVDF are commonly used in high-purity fluid handling and corrosion-resistant applications. Final selection must consider chemical type, concentration, temperature, pressure, mechanical stress, purity requirements, and contamination-control requirements.

Wafer Handling: Static Control and Particle Management

During wafer handling, transfer, and robotic gripping, contact and separation between materials can generate static charge. Charged surfaces may attract airborne particles, while electrostatic discharge can damage ESD-sensitive devices.
Around FOUPs, guide rollers, sliding components, and fixture mounting points, static-dissipative PEEK, ESD-grade POM, and other suitable materials can be evaluated.

Vacuum & High-Temperature Environments: Dimensional Stability and Low-Outgassing Requirements

CVD, PVD, plasma etching, and other vacuum processes vary significantly in temperature, pressure, process gas, and plasma conditions. Component materials therefore depend strongly on installation location and exposure conditions.
Selected PEEK and PI grades can be evaluated for components around vacuum equipment where heat resistance, dimensional stability, low outgassing, and mechanical performance are required.

Packaging/Test & Precision Inspection Equipment: Electrical Insulation and Dimensional Control

Test sockets, probe-station assemblies, and precision automation systems often require tight dimensional tolerances, electrical insulation, mechanical stiffness, and thermal stability. Engineering plastic screws, standoffs, insulating sleeves, and locating components can provide electrical isolation and precision support at selected locations, reducing the risk of unintended conductive paths and short circuits.
