PTFE wafer basket, for square wafer

About PTFE wafer basket, for square wafer

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.

Precision Craftsmanship for Superior Wafer Protection

Our PTFE wafer baskets are meticulously engineered to ensure every square wafer is housed in its own groove, maintaining separation and safeguarding fragile edges. The smooth virgin PTFE construction avoids contaminating particles, while the slot design supports swift, secure placement and removal.


Custom Fit for All Square Wafer Needs

With flexibility to accommodate standard and custom wafer dimensions, our baskets are designed based on your specific requirements, including groove pitch, wall thickness, and overall basket size. Typical groove pitches of 2.0-2.5 mm and wall thickness of 3-5 mm ensure optimal stability and protection for your wafers.


Engineered for Chemical Purity and Versatility

Constructed from virgin PTFE, the basket resists all acids, bases, and solvents commonly found in semiconductor processes. Its anti-adhesive, ultra-smooth surface makes cleaning simple, and ensures compliance with the strictest cleanroom and RoHS standards. Safe for temperatures from -200C to +260C and compatible with sterilization processes, it's the ideal solution for ultra-pure environments.
