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

Product Overview

This high-purity PTFE circular wafer carrier is an essential instrument for semiconductor wet processing and advanced laboratory cleaning protocols. Engineered specifically for 6-inch substrates, the equipment serves as a robust and chemically inert vessel that facilitates uniform fluid exposure during critical etching, rinsing, and stripping phases. By utilizing virgin fluoropolymer materials, this unit ensures that delicate silicon or GaAs wafers are protected from mechanical stress and metal-ion contamination, maintaining the integrity of sensitive microelectronic architectures.

Primarily utilized within semiconductor fabrication cleanrooms, photovoltaic cell production lines, and high-level analytical chemistry labs, the system excels in environments where traditional plastic, glass, or metal carriers would fail. The circular "flower basket" design is optimized for immersion-based operations, allowing for maximum surface area contact between the cleaning agents and the substrates. This design philosophy is critical for achieving the high-yield outcomes required in modern electronics manufacturing.

Buyers can invest in this system with total confidence, knowing it is backed by precision CNC fabrication and an absolute focus on material purity. The inherent properties of the fluoropolymer construction—including its non-stick surface and extreme thermal stability—ensure a long service life even under continuous exposure to aggressive chemical baths. This unit represents a high-performance solution for facilities that prioritize reliability, repeatability, and zero-contamination in their wet bench processes.

Key Features

• Superior Chemical Universalism: Fabricated from 100% virgin PTFE, this system resists virtually all industrial solvents, strong acids (including HF and Piranha), and concentrated alkalis, ensuring no degradation over years of service.
• Precision Slotted Geometry: The internal carrier structure features CNC-machined slots with optimized pitch and depth to secure 6-inch wafers while maximizing the flow of etching or rinsing fluids across the substrate surface.
• High-Temperature Operational Range: The equipment maintains its structural integrity and dimensional stability at temperatures ranging from cryogenic levels up to 260°C, making it suitable for heated chemical baths.
• Zero-Contamination Profile: The non-leaching characteristics of the material prevent the introduction of trace metals or organic extractables, which is critical for maintaining sub-ppb purity levels in semiconductor processing.
• Enhanced Fluid Dynamics: The circular basket design, often referred to as a flower basket, incorporates perforated or slotted walls that prevent fluid stagnation and promote uniform chemical concentration throughout the bath.
• Low-Friction Surface Protection: The naturally slippery surface of the carrier prevents scratching or mechanical damage to the wafer edges during loading and unloading, reducing scrap rates in high-volume production.
• Robust Monolithic Construction: Unlike molded alternatives, this unit is often machined from a single block of high-density PTFE, eliminating weak points, seams, or potential areas for particle entrapment.
• Customizable Configuration: The system can be tailored with specific slot counts, handle lengths, or structural reinforcements to meet the unique requirements of bespoke wet bench setups or automated handling tools.
