It is amusing so many commentators cannot communicate novel materials science in Korean to the layperson. Where's your zero resistivity sample? The paper is just a guide. Who would replicate likely needs to contact the authors to understand the implicit details of the recipe. That is process knowledge. There's a good reason world-leading lithography happens in that region. With luck, researchers and engineers will be able to refine and industrialize the process these coming years.
