Yet unlike software, where industry leadership can shift in a matter of months, success in lithography is a slow-moving race ...
“The SHARP project aims to lead to new manufacturing technologies that enable large-area mirrors with novel properties,” said Dr. Yakup Gönüllü from Schott. He is coordinating the new joint project, ...
That has improved, but power efficiency remains a major issue.” Much of this is due to the fact that EUV scanners contain 6 mirrors. “The more mirrors in the optical path, the more energy is lost,” ...

American lab is developing a BAT laser that could enable 'beyond EUV' lithography, provide 10X power efficiency boostIn addition, vacuum requirements to prevent the absorption of EUV light by air add to the overall energy use. Finally, as advanced mirrors in EUV tools reflect only a fraction of EUV light ...
The most significant of these are the efficiency of the EUV production, the reflectivity of mirrors and the continuous, high-repetition rate operation of lithography systems. The best tin-based ...
Even with these coatings, each mirror can only reflect a theoretical maximum of 72% of the incident EUV light — the rest is absorbed by the mirror. To get close to this theoretical level and to ...
In a lithography tool such as ASML’s, the EUV beam bounces off nearly a dozen mirrors before it hits the silicon. EUV light is so easily absorbed, though, that even in a vacuum-sealed chamber ...
