If you don’t find what you are looking for here, contact H-Square to discuss your needs and requirements.

Thermal Process Aluminum Cassettes
H-Square is the oldest and most experienced semiconductor high-temperature aluminum wafer cassettes manufacturer. The AMC cassette has proven to provide the best reliability, performance, service life, and value compared to any competitor’s product. In addition, cassettes can be ordered in various sizes, slot configurations, wafer stop materials, and surfacefinish, giving users many options to meet their specific requirements.

Thermal Process Stainless Steel and Aluminum Cassettes
These cassettes are made for high-temperature wafer processing applications or specialty applications. Available for 76-300mm wafer sizes and Thermal Environments up to 550°C.

Fuji Bakelite Plastic Process Cassettes and Cases
Fuji Bakelite Co. Ltd Japan manufactures a unique product line of high-quality cassettes and WIP storage cases with new FB-0431 material specifically designed for the semiconductor industry. FB-0431 is an antistatic cyclicolefin copolymer with milled carbon fiber, which is specially compounded and developed as an upgraded material to PP, PC, and PBT and a lower-cost alternative to PEEK. FB-0431 performance is comparable to antistatic PEEK at a fraction of the cost and superior abrasion resistance.

Fuji Bakelite products are tomorrow’s standard for semiconductor wafer handling, they feature:
• Automation setup - superior dimensional stability; exact repeatability from cassette to
• Micro-contamination - unmatched abrasion resistance; lower particle generation
• ESD-safety - consistent resistivity throughout the product
• Yield improvements - FB cases eliminate the high particle shedding common with all competitor
