In a method form manufacturing a photomask, the method includes coating an organometallic ink on a base substrate to form a solution layer. The base substrate is heat-treated on which the solution layer is formed, to self-produce a nanoparticle in the solution layer. A laser is irradiated to the solution layer, to form a metal pattern. The solution layer having the metal pattern is cleaned. The metal pattern is heat-treated. The metal pattern is covered using an encapsulant. |
