Engineered Pedestal for High-NA EUV Lithography

Overview

Tool Platform: High-NA EUV lithography system

Solution: Custom-engineered, large-format pedestal

Primary Benefit: Absolute stability for picometer-level accuracy

Application: Advanced-node semiconductor manufacturing

Customer & Application

Fulcrum engineered a custom pedestal to support the next generation of High-NA EUV lithography systems developed by ASML, enabling unprecedented precision in advanced semiconductor manufacturing. The pedestal was designed specifically for the TWINSCAN EXE:5200, one of the most complex and demanding tools ever deployed in a fab environment.

Challenge: Stability at Unmatched Scale

High-NA EUV lithography introduces extreme structural demands, including immense system weight, dense load distribution, and picometer-level accuracy requirements. Even minor vibration or deflection could compromise tool performance. The customer required a pedestal capable of delivering absolute stability across a large footprint while accommodating multiple complex tool modules with precise mounting interfaces.

Fulcrum’s Engineered Solution

Fulcrum designed a large-format, heavily reinforced pedestal engineered to eliminate vibration and evenly distribute the system’s substantial mass. A dense array of support points provided exceptional stiffness, while the meticulously planned top surface featured precision-located interfaces to integrate all EXE:5200 modules seamlessly. The result was a foundation engineered to support picometer-level accuracy in one of the most advanced lithography platforms ever built.
