Third-generation semiconductor cleaning equipment (SiC, GaN) faces severe space constraints. Standard FFUs at 250–350mm simply cannot fit into the limited vertical clearance of these advanced tools. This article introduces DSX's 70mm Ultra-Thin EFU—engineered specifically for space-constrained equipment integration. With a total operational thickness of ~100mm, ULPA filtration efficiency up to 99.9995% (@0.12μm), and full-supply-chain manufacturing, this solution enables cleaning equipment manufacturers to maximize internal space without compromising cleanroom performance.
 

This article provides a comprehensive overview of ultra-thin EFU (Equipment Fan Filter Unit) technology for semiconductor manufacturing equipment. It addresses the critical challenge of limited internal space in advanced semiconductor tools, where standard FFUs cannot fit. The solution – a 70mm ultra-thin EFU – is introduced, with detailed explanations of how full-supply-chain manufacturing enables this breakthrough through custom-engineered EC brushless micro-fans, self-manufactured mini-pleat HEPA/ULPA filters, and optimized internal geometry. Key technical specifications, AMC contamination control, smart control capabilities, and application scenarios across front-end and back-end equipment are covered.
