EUV lithography is governed by operational currencies.

From wafers per hour to stochastic defect rates and downtime cost, these KPIs define what is technically possible and economically viable.

This episode decodes the most important EUV-relevant metrics and their trade-offs.

Key Takeaways

- WPH reflects physics, chemistry, and system efficiency

- Availability often matters more than peak throughput

- EUV yield is limited by stochastic effects

- Dose links pattern quality to productivity

- Downtime cost strongly shapes EUV economics

Glossary

WPH: Wafers processed per hour

OEE: Overall equipment effectiveness

Overlay: Layer-to-layer alignment accuracy

DOF: Depth of focus tolerance

COO: Cost of ownership
