About PTFE wafer cassette, for 150*150mm, 25 slots, with handle

Product Overview

This specialized PTFE Wafer Basket is engineered for precision cleaning and etching of individual substrates or small batches. Unlike large-scale carriers, this compact, vertical-handle design allows operators to maintain maximum control during delicate dipping processes. The pure white PTFE construction ensures a "metal-free" environment, preventing the leaching of impurities that could compromise semiconductor electrical properties. Whether you are using the slotted rectangular base for edge-only contact or the perforated circular base for optimized fluid turbulence, these baskets provide a stable and non-reactive housing for high-value wafers.

Bespoke Customization Services

We specialize in tailoring these baskets to your specific wet-bench requirements:

Custom Base Styles: Choose between a slotted V-bridge (for minimum contact) or a perforated disk (for maximum stability).
Adjustable Handle Length: Handles can be extended or shortened to match the liquid levels of your specific PFA or PTFE cleaning tanks.
Tailored Wafer Fit: Precision-sized for standard 1-inch to 8-inch wafers, or customized for square substrates and optical components.
Multi-Slot Expansion: The base can be modified to hold multiple wafers in a parallel or back-to-back configuration.

Product Synergy & Workflow

Designed to integrate into a professional high-purity cleaning station:

PFA/PTFE Cleaning Tanks: The vertical handle design is optimized for use in deep, narrow-mouth cleaning jars and tanks.
Inert Hot Plates: Ideal for processes requiring heated chemical baths, as the PTFE material remains stable up to 260C.
PTFE Tweezers: Used for the precise placement and removal of wafers from the basket slots without scratching the surface.
PFA Fittings & Tubing: Essential for constructing the ultra-pure water (UPW) rinsing lines used after the chemical etch.

Application Fields & Industries

R&D Laboratory Scale: Ideal for university research and small-scale pilot lines where individual wafer processing is required.
Semiconductor Wet Etching: Safe handling during hydrofluoric acid (HF) dipping or buffered oxide etch (BOE) steps.
MEMS & Micro-Optics: Processing of specialized sensors, sapphire windows, and quartz substrates.
Thin-Film Deposition Prep: Ensuring a pristine, particle-free surface prior to CVD or PVD processes.

Superior Corrosion Resistance

Constructed entirely from PTFE, this wafer cassette offers remarkable resistance to acids, bases, and solvents typically used in laboratory cleaning processes. Its durability extends the lifespan of your equipment while maintaining the integrity of delicate wafers.

Contamination-Free Handling

The cassette's PTFE composition ensures chemical inertness, significantly reducing the risk of particle or chemical contamination. This is crucial for sensitive lab procedures, where even minimal contamination could compromise experimental results or device performance.

FAQ's of PTFE wafer cassette, for 150*150mm, 25 slots, with handle:

Q: How is the PTFE wafer cassette used in laboratory wafer cleaning?

A: The cassette holds up to 25 wafers securely during cleaning processes, allowing easy transfer and organization. Its corrosion resistance ensures compatibility with various cleaning chemicals without the risk of leaching or contamination.

Q: What are the primary benefits of using a PTFE wafer cassette in laboratory environments?

A: Key benefits include exceptional corrosion resistance, prevention of wafer contamination, ease of handling due to its integrated handle, and suitability for cleanroom operations, making it ideal for sensitive lab work.

Q: When should I choose a PTFE wafer cassette over other materials?

A: Select PTFE wafer cassettes when your process requires strong chemical resistance and zero contamination risk, particularly in wafer cleaning or chemical processing environments.

Q: Where is the PTFE wafer cassette mainly applied?

A: These cassettes are mostly used in semiconductor laboratories and research facilities, specifically for cleaning and safely storing 150x150mm silicon wafers.

Q: What steps are involved in the wafer cleaning process using this cassette?

A: Place up to 25 wafers in the cassette, secure them in position, and immerse the cassette in the cleaning solution. The handle facilitates safe transfer between cleaning and rinsing stages without touching the wafers.

Q: How does the cassette's design benefit the wafer handling process?

A: The dedicated handle allows for comfortable, stable transport, while the spacing between slots ensures wafers do not touch or scratch each other, preventing physical damage and maintaining surface quality.
