PTFE wafer cassette, for 7", 25 slots, with Y type handle

About PTFE wafer cassette, for 7", 25 slots, with Y type 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.
