ZEISS Creates the Smoothest Mirrors Ever: Hardcore Specs of EUV Lithography
DynamicWebPaige · x · 2026-08-11
The post cites hardcore technical details regarding the mirrors ZEISS manufactured for ASML's EUV lithography machines:
- Extreme Smoothness: These mirrors are the smoothest objects ever made, with almost imperceptibly small impurities. If scaled to the size of Germany, their biggest irregularities would be just a tenth of a millimeter.
- Precision Control: To direct EUV light precisely, the mirrors must be held perfectly still, requiring mechanics and sensors so exact they could aim a laser to hit a golf ball on the moon.
