VSJOCO
A PVDF wafer carrier is a precision-machined tray designed to hold individual silicon wafers in separate slots during manufacturing, transport and storage. Its primary function is to isolate wafers from physical contact with external surfaces and environmental contaminants, while maintaining structural integrity during automated handling processes. Each carrier is dimensionally calibrated to ensure precise alignment with production equipment, minimizing the risk of wafer breakage or process interruptions.
Unlike alternative materials such as polypropylene (PP), polyether ether ketone (PEEK) and polytetrafluoroethylene (PTFE), PVDF delivers a balanced combination of properties tailored to semiconductor manufacturing requirements. PP offers limited chemical resistance and degrades rapidly under repeated cleaning cycles. PEEK provides mechanical strength but comes with higher material costs and elevated leachable levels. PTFE exhibits excellent chemical inertness but lacks sufficient mechanical stability for automated systems. PVDF resolves these tradeoffs, making it the preferred material for high-volume wafer processing.
VSJOCO wafer carriers withstand repeated exposure to strong acids, alkalis and organic solvents used in semiconductor wet processes. Testing confirms performance remains consistent after 1000+ standard SC1/SC2 cleaning cycles. This resistance allows carriers to operate reliably in harsh chemical environments, reducing replacement frequency and associated production downtime.
Manufactured to SEMI F57 high-purity standards, our PVDF carriers demonstrate metal ion leaching levels below 1ppb as verified by ICP-MS analysis. Particle release is controlled to less than 0.1 particles per square centimeter for particles measuring 0.2μm or larger. These low leachable and particle characteristics prevent wafer contamination, directly contributing to improved product yields for manufacturing clients.
The carriers maintain structural integrity across a temperature range of -40°C to 150°C. This dimensional stability ensures consistent performance during high-temperature process steps and automated handling operations, eliminating risks of equipment jamming or wafer breakage caused by material deformation.
PVDF exhibits natural anti-static characteristics with a surface resistivity of 10×10^9 - 10×10^11 Ω/sq. Unlike carriers that require added anti-static agents, our PVDF carriers eliminate the risk of secondary contamination from additive leaching, while providing reliable protection for sensitive circuit structures against electrostatic discharge.
