Web9 feb. 2015 · 1. Irradiation: The first step in x- ray lithography is irradiation which involves exposing a thick layer of resist to high- energy beam of x-rays from a synchrotron. The mask membrane is normally a low atomic number material such as diamond, beryllium, or a thin membrane of a higher atomic number material such as silicon or silicon carbide. 2. Lithography (from Ancient Greek λίθος, lithos 'stone', and γράφειν, graphein 'to write') is a planographic method of printing originally based on the immiscibility of oil and water. The printing is from a stone (lithographic limestone) or a metal plate with a smooth surface.
