A method of manufacturing an ink jet printhead, including: arranging a nozzle plate in which there is formed a plurality of nozzles, the nozzle plate having an upper surface and a lower surface, the upper surface being on the side of the ejection of ink drops and the lower surface being opposite to the upper surface; depositing on the upper surface a first coating including a first layer including silicon carbide, while maintaining the nozzle plate at a first deposition temperature not larger than 250° C.; depositing on the lower surface a second coating including a second layer including silicon carbide, while maintaining the nozzle plate at a second deposition temperature not larger than 250° C.; positioning the nozzle plate onto the ink barrier layer by bringing into contact the second coating layer with the ink barrier layer. The first layer is deposited before the second layer.
