However, some metasurface differentiators are limited by polarization dependence, narrow operating bandwidth, low numerical aperture (NA), requiring for additional polarization elements or digital ...

Intel seems to have a clear advantage by moving to high-NA before its competitors, which still use "low" numerical aperture extreme ultraviolet (EUV).

The future of computing depends on miniaturization, and extreme ultraviolet lithography (EUV) is one key enabler. Until recently, we have relied on low numerical aperture (NA) EUV systems with an ...

Until recently, we have relied on low numerical aperture (NA) EUV systems with an aperture of 0.33 to help us reduce the size of integrated circuits (ICs). As with deep ultraviolet (DUV) technology, ...
