"Ptychography works by scanning overlapping scattering patterns from a material sample and looking for changes in the overlapping region" Interesting, we use multi-patterning to produce silicon already to get the light down to scale for process nodes - this is kinda the reverse and do wonder if some of this research may have applications in silicon production.
