New EUV Lithography System Promises Higher Throughput and Sub-10nm Feature Resolution

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel two-mirror projection system for extreme ultraviolet (EUV) lithography, capable of achieving a 4x demagnification at wavelengths of 13.5 nm and 11.2 nm. This design significantly improves optical throughput compared to conventional systems, retaining 50-60% of the power leaving the mask. The system utilizes individually optimized Bragg multilayer coatings and has demonstrated the ability to simulate aerial images of sub-10-nm features, including isolated peaks and 6-nm line pairs, with high resolution.

    A Two-Mirror Faceted Projection System for EUV Lithography

    arXiv:2609.11299v1 Announce Type: cross Abstract: We propose an all-reflective two-mirror projection system for extreme ultraviolet (EUV) lithography operating at exposure wavelengths of $13.5$~nm (Mo/Si) and $11.2$~nm (Ru/Be), delivering a fourfold ($4\times$) demagnification of…
