Abstract
A nozzle plate, inkjet head a manufacturing method of the same are disclosed. By using a method of manufacturing a nozzle plate which includes: forming a nozzle by selectively etching one side of a plate substrate, forming a straight portion connecting with the nozzle by selectively etching the other side of the plate substrate, and forming a hydrophobic layer on the one side of the plate substrate, where a window is formed in the hydrophobic layer that opens the nozzle by a circumference greater than a circumference of an end of the nozzle, the meniscus of ink can be formed to a greater size around the nozzle exit, thereby preventing degradations in ink ejection performance due to the vaporization of the solvent, and preventing blockage in the nozzles due to the clogging of particles.
