Abstract: An inkjet printer head and fabricating method thereof are disclosed. An inkjet printer head, which includes: a lower board, in which a nozzle part and a restrictor are formed; an upper board attached to an upper portion of the lower board, in which an ink chamber and an ink inlet are formed; and a piezoelectric element joined to a membrane of the upper board, where the membrane is formed by the portions remaining after portions of the upper board are removed to form the ink chamber, is formed by attaching two boards by an attachment method that does not use a separate adhesion material, such as anodic bonding, for a simple and easy attachment, and for a strong head structure in which there are no chemical or physical reactions that may occur in adhesion layers.

Abstract: A method of manufacturing a nozzle for an inkjet head is disclosed. With the method of manufacturing a nozzle for an inkjet head, comprising (a) coating photoresist on an inkjet head structure comprising a nozzle part; (b) adjusting exposure conditions and performing exposure and developing on the nozzle part to remove a portion of the photoresist; (c) joining a hydrophobic layer onto the portion of the nozzle part where the photoresist has been removed; and (d) removing the photoresist remaining on the nozzle part, it is easy to control the depth of the hydrophobic layer to be uniform, and the depth to which the hydrophobic layer is deposited may be controlled even when the back surface of the nozzle has a complex shape, so that the uniformity and reproduction of the hydrophobicity-treated nozzles are improved.
