PTFE (polytetrafluoroethylene) wafer carriers are another type of specialized containers used in the semiconductor industry to hold and transport semiconductor wafers during various stages of the production process. PTFE is a high-performance polymer that provides excellent chemical and thermal resistance, making it ideal for use in the harsh chemical and high-temperature environments common in semiconductor manufacturing.
PTFE wafer carriers come in a variety of sizes to accommodate different wafer diameters, typically ranging from 2 inches to 12 inches. Like PFA wafer carriers, they are designed to securely hold and protect the delicate wafers during transportation and processing, preventing damage from vibration, shock, or contamination. PTFE wafer carriers are also resistant to many of the harsh chemicals used in semiconductor processing, such as acids and solvents, which can corrode or degrade other materials.
One advantage of PTFE wafer carriers is their high purity and low particle generation, which helps to minimize contamination and improve yield in semiconductor manufacturing. They are also highly durable and can withstand repeated exposure to high temperatures and harsh chemicals, making them a cost-effective and reliable option for long-term use.
PTFE wafer carriers are an important component of the semiconductor manufacturing process, providing a safe and reliable means of transporting and protecting delicate wafers throughout the production process.
