Exceptional Chemical Inertness: Fabricated from 100% high-purity PTFE, providing total resistance to concentrated HF, H2SO4, and BOE (Buffered Oxide Etch).
Optimized Fluid Dynamics: Engineered with precision-milled slots and an open-frame design to ensure maximum chemical circulation and uniform rinsing.
Surface Protection: The ultra-smooth, non-stick PTFE surface prevents wafer scratching and minimizes particle adhesion during processing.
Thermal Stability: Maintains structural integrity in high-temperature chemical baths up to 250°C.
Bespoke Customization: Fully tailorable slot pitch, pocket depth, and overall dimensions to accommodate any wafer size (2", 4", 6", 8") or non-standard substrate.

6", 5 slots, with Y type handleThe PTFE Wafer Cassette (also known as a wafer carrier) is a critical component for wet-process stations in semiconductor and micro-electronics manufacturing. Unlike standard plastic carriers that may degrade or shed particles in aggressive etchants, our PTFE baskets offer a "metal-free" and virtually indestructible housing for sensitive substrates. The design prioritizes minimal contact points to prevent "shadowing" during etching and cleaning, ensuring that every square millimeter of the wafer surface is exposed to the process chemicals consistently.
We recognize that every fabrication process has unique requirements. Our engineering team can provide:
Tailored Wafer Capacities: Custom baskets designed to hold 5, 10, 25, or any specific number of wafers per batch.
Specialized Slot Geometry: Adjustable slot widths and angles to secure ultra-thin wafers or thick optical glass substrates.
Integrated Handle Interfaces: Precision-machined attachment points for compatibility with our Y-Type or M-Type PFA Handles.
Dimension Matching: Custom footprint designs to fit perfectly into existing PFA tanks, ultrasonic cleaners, or automated spin-dryers.
Optimized for high-purity semiconductor cleaning chains:
PFA Y-Type & M-Type Handles: Provides the safe and inert interface for manual or robotic transport of the basket between baths.
PFA/PTFE Cleaning Tanks: The basket is designed to be submerged in these tanks for batch etching or rinsing.
PTFE Shovels & Tweezers: Used for the careful loading and unloading of substrates into the basket slots.
PFA Fittings & Tubing: Integrated into the rinsing stations where the loaded basket is subjected to ultra-pure water (UPW) flow.
Semiconductor Fabrication: Cleaning, etching, and stripping of silicon wafers in front-end-of-line (FEOL) processes.
MEMS & Sensors: Handling of delicate micro-electromechanical systems during wet-chemical release steps.
Optoelectronics: Batch cleaning of high-purity lenses, quartz plates, and sapphire substrates.
Solar Cell (PV) Manufacturing: Processing of silicon wafers through texturing and phosphorus removal baths.
