Where the article explains it
Substitute the vendor’s own numbers back into the relation and the implied is about 0.27, within a few per cent of the two-beam floor.
The passage around this formula
…its current 193 nm immersion platform, quoting production resolutions down to 40 nm with quadrupole illumination and 38 nm with dipole [ 8 ] . Substitute the vendor’s own numbers back into the relation and the implied is about 0.27, within a few per cent of the two-beam floor. There is nothing meaningful left to extract from that configuration. Below roughly 38 nm in a single exposure, either the wavelength changes or the pattern is built from more than one exposure.
