Re: understatement

Mostly because actual Xray photons (defined as between 10 nm and 0.01 nm wavelength) were found to knock loose too many electrons in the resist material and cause fuzzy edges, negating the minimum feature size gain. This is still a problem with EUV (13,5 nm wavelength) but to a lesser extend.
