High Purity PTFE Wafer Cleaning Basket Acid Resistant Silicon Wafer Carrier Fluoropolymer Etching Rack

Product Overview

This high-purity fluoropolymer carrier system is engineered specifically for the rigorous demands of the semiconductor and microelectronics industries. Designed to facilitate the safe and efficient handling of delicate silicon wafers during wet chemical processing, this unit serves as a critical interface between complex chemical baths and sensitive substrates. By utilizing premium-grade polytetrafluoroethylene (PTFE), the system provides an inert environment that prevents metallic contamination and ensures that the integrity of the wafers is maintained throughout etching, cleaning, and rinsing cycles.

The equipment is primarily utilized in cleanroom environments for high-stakes operations such as RCA cleaning, Piranha etching, and hydrofluoric acid (HF) dips. Beyond standard silicon processing, this unit is equally effective for compound semiconductors like Gallium Arsenide (GaAs) and solar cell production. Whether integrated into automated wet benches or used in manual immersion tanks, the system's robust construction and specialized geometry promote uniform chemical exposure and rapid drainage, making it an indispensable tool for achieving high yield and process consistency.

Built for long-term reliability in the harshest industrial environments, this equipment offers unparalleled resistance to strong acids, bases, and organic solvents. The inherent non-stick properties of the material minimize particle adhesion and facilitate easy decontamination between batches. Our commitment to precision engineering ensures that every carrier provides a secure fit for the wafers while allowing for maximum fluid dynamics, providing engineers and lab managers with the confidence that their most valuable substrates are protected under the most demanding thermal and chemical conditions.

Key Features

• Superior Chemical Universal Resistance: Crafted from high-density PTFE, this unit is completely inert to virtually all aggressive chemicals, including concentrated sulfuric acid, hydrofluoric acid, and strong alkaline solutions, ensuring zero leaching and a long service life.
• High-Temperature Thermal Stability: The system maintains its structural integrity and dimensional accuracy across a wide temperature range, allowing for consistent performance in boiling acid baths or high-temperature rinsing stages.
• Precision-Machined Wafer Slots: Each slot is CNC-machined to exact tolerances to ensure minimal contact with the wafer surface while providing secure support, preventing mechanical stress and scratching during transport and immersion.
• Optimized Fluid Dynamics: The "flower basket" geometry is engineered to facilitate laminar flow during chemical circulation and ensure rapid, streak-free drainage when the unit is lifted from the bath, reducing cross-contamination risks.
• Integrated Ergonomic Handle Design: Featuring robust, customizable handles, the equipment allows for safe manual handling or seamless integration with robotic grippers, ensuring stability during high-speed transfers.
• Ultra-Low Surface Energy: The naturally hydrophobic and non-stick surface of the material prevents the build-up of process residues and simplifies the cleaning protocol, maintaining the high purity standards required for trace analysis and sub-micron fabrication.
• Customizable Configuration: We offer end-to-end customization for slot pitch, quantity, and overall dimensions, allowing the system to be tailored to specific wafer thicknesses and unique process vessel requirements.
• Particle Contamination Control: The smooth, pore-free surface finish minimizes areas where particles can hide, ensuring that the equipment meets the strictest Class 10 and Class 100 cleanroom standards.
• Structural Durability: Unlike molded alternatives, our machined fluoropolymer carriers offer superior mechanical strength and resistance to warping, even after repeated exposure to thermal cycling in corrosive environments.
