FEP Resin For Wire And Cable Insulation

PFA sheets and rods have become an indispensable functional material in semiconductor manufacturing due to their excellent chemical stability, high purity, and resistance to extreme environments. They are mainly used in the following processes.

I. Wet Process Equipment Components

● Etching/Cleaning Baskets and Brackets: PFA sheets and rods are made into baskets, clamps and other support tools to stably fix wafers in a mixture of hydrofluoric acid and nitric acid (25℃–130℃), avoiding metal contamination while withstanding strong corrosive media.

● Piping and Valves: Fluid delivery systems made of high-purity PFA prevent particle precipitation and meet the cleanliness requirements of SEMI F57 standards for ultrapure water systems.

II. Wafer Carrier and Fixing

● Carriers and fixtures: The wafer supports processed by PFA sheets and rods can maintain dimensional stability in high-temperature environments (-200℃ to 260℃), avoiding microlithography alignment deviations caused by thermal deformation.

● Vacuum chuck pads: Their low gas release characteristics (total mass loss TML < 0.1%) meet the requirements of high-vacuum lithography machines.

III. Special Environmental Protection

● CMP (Chemical Mechanical Polishing) Equipment: PFA baffles prevent polishing slurry splashing, extending equipment life.

● Reaction Chamber Lining: The lining processed by PFA sheets and rods can withstand continuous scouring by Cl₂/Ar plasma at 200℃ and can withstand more than 20 thermal cycles per day, effectively reducing the risk of particle release and arc discharge.

Summary

PFA sheets and rods play an irreplaceable role in key stages of semiconductor manufacturing due to their superior corrosion resistance, high purity, and thermal stability. As semiconductor processes evolve towards more refined fabrication methods, performance optimization of PFA materials will continue to drive technological advancements in the industry, providing a solid guarantee for improved reliability and yield in wafer production. The future application potential of PFA sheets and rods in new process equipment and green manufacturing is worthy further exploring.
