NexGen Wafer Systems announced the launch of SERENO, its latest multi-chamber platform designed for Wet Etch and Clean applications.
SERENO combines high performance with exceptional flexibility, offering integrated metrology for precise substrate and layer thickness control, as well as surface roughness control. Its onboard chemical supply system supports multiple process chemicals with integrated mixing, blending, and comprehensive analytics, ensuring maximum adaptability across a wide range of applications.
With a compact footprint of less than 12 m² and a throughput of up to 200 wafers per hour, SERENO is designed to deliver unmatched efficiency and versatility in wet chemical processes. Tailored for both FEOL and BEOL applications, SERENO addresses the semiconductor industry’s increasing demands for higher performance, precision, and cost efficiency, positioning it as a future-proof solution for evolving manufacturing requirements.
Delivering High Performance in a Compact Design
The SERENO platform offers maximum flexibility regarding wafer-handling capabilities and process control. It supports various substrate types for 6″, 8” and 12″ wafers. Its versatile handling system supports wafer thicknesses ranging from ultra-thin wafers below 100µm to bonded wafers exceeding 2mm in total thickness. High-performance process chambers combined with innovative chemical dispensing and scanning control offer maximum freedom, leading to outstanding on-wafer performance.
“With SERENO, we provide Wet Etch and Clean solutions that deliver high throughput in a compact footprint while maximising the flexibility and performance advantages of Single-Wafer Technology,” said Christian Kleindienst, Chief Marketing Officer at NexGen Wafer Systems. “Our SERENO platform addresses our customers’ demand for flexible, high-performance Single-Wafer solutions that reduce operational costs and present a highly attractive alternative to traditional batch tools.”
