Abstract
A method of forming a hydrophobic coating layer on a surface of a nozzle plate of an inkjet printhead includes forming a plurality of nozzles in the nozzle plate, each of the nozzles having an exit, stacking a film on the surface of the nozzle plate to cover the exit of each of the nozzles, forming a predetermined metal layer on an inner wall of each of the nozzles and an inner surface of the film covering the exit of each of the nozzles using a plating method, removing the film from the surface of the nozzle plate, forming a hydrophobic coating layer on the surface of the nozzle plate to cover the metal layer exposed through the exit of each of the nozzles, and removing the metal layer formed on the inner wall of each of the nozzles and the hydrophobic coating layer formed on the surface of the metal layer.
