PTFE Circular Wafer Carrier 6 Inch Acid Alkali Resistant Semiconductor Cleaning Basket Customizable

Product Overview

This high-purity substrate handling system is engineered specifically for the rigorous demands of semiconductor fabrication and advanced wet chemistry environments. Designed to facilitate the safe and efficient cleaning, etching, and rinsing of 6-inch (150mm) wafers, this unit serves as a critical interface between delicate silicon substrates and aggressive chemical reagents. By utilizing premium-grade fluoropolymer construction, the system ensures that contamination risks are minimized while maintaining structural integrity in the most volatile processing conditions. The circular geometry is optimized for compatibility with standard process tanks, providing a secure and stable platform for high-value components.

Primarily utilized in the microelectronics, solar energy, and compound semiconductor industries, the equipment excels in multi-stage cleaning protocols including RCA clean, piranha etching, and hydrofluoric acid (HF) dips. It is indispensable for facilities performing photolithography, chemical mechanical polishing (CMP) post-processing, and ultrasonic substrate agitation. The design focuses on maximizing fluid exchange and drainage, ensuring that reagents contact every surface of the wafer uniformly while preventing the entrapment of contaminants or stagnant liquid between processing steps.

Engineers and procurement teams can rely on this unit for long-term operational consistency. Unlike standard plastics that may degrade or leach ions when exposed to concentrated acids and elevated temperatures, this system leverages the unique molecular stability of high-performance fluoropolymers. The result is a robust, non-reactive carrier that withstands repeated thermal cycling and prolonged immersion without compromising the purity of the chemical bath or the integrity of the wafers being processed. Every unit is a testament to precision CNC fabrication, reflecting a commitment to technical excellence in laboratory and industrial fluid handling.

Key Features

• Superior Chemical Inertness: Constructed from premium PTFE, the system is virtually unaffected by almost all industrial chemicals, including concentrated sulfuric acid, nitric acid, and strong alkaline solutions, ensuring zero contamination of the process stream.
• Optimized Fluid Dynamics: The carrier features precision-machined slots and flow-through ports designed to facilitate rapid reagent penetration and complete drainage, which is essential for uniform etching and streak-free drying.
• Thermal Stability Range: This unit maintains its mechanical strength and dimensional stability across a wide temperature spectrum, allowing for seamless transition between chilled etching baths and heated cleaning cycles without warping.
• Low Surface Energy: The naturally non-stick properties of the fluoropolymer material prevent the adhesion of particulates and organic residues, making the equipment easy to clean and maintain at semiconductor-grade purity levels.
• Precision CNC Fabrication: Each basket is manufactured using advanced CNC machining techniques, ensuring ultra-smooth surfaces and tight tolerances that prevent physical stress or scratching on delicate wafer edges.
• High-Purity Material Sourcing: We utilize only virgin, high-molecular-weight PTFE, which is inherently free of fillers, pigments, and metallic impurities, meeting the stringent requirements of sub-micron fabrication facilities.
• Ergonomic and Modular Design: The circular frame is engineered for easy manual handling or integration with automated robotic arms, featuring secure grip points that minimize the risk of operator error during high-stakes transfers.
• Mechanical Durability: Despite its chemical softness, the structural design of the basket provides excellent impact resistance and load-bearing capacity, ensuring it can support full batches of wafers through high-speed rinsing or ultrasonic agitation.
