In this paper, we report a cathode metal patterning method by the surface energy control of organic material in thermal evaporation process. In order to make the self-metal patterning, a metal patterning layer (MPL) was introduced before the metal deposition. Among several MPLs, the lowest surface energy materials result in excellent patterning properties in both Mg as well as Ag.
