Abstract
A method for manufacturing the same, wherein the monolithic ink-jet printhead includes a manifold for supplying ink, an ink chamber having a hemispheric shape, and an ink channel formed monolithically on a substrate; a silicon oxide layer, in which a nozzle for ejecting ink is centrally formed in the ink chamber, is deposited on the substrate; a heater having a ring shape is formed on the silicon oxide layer to surround the nozzle; a MOS integrated circuit is mounted on the substrate to drive the heater and includes a MOSFET and electrodes connected to the heater. The silicon oxide layer, the heater, and the MOS integrated circuit are formed monolithically on the substrate. Additionally, a DLC coating layer having a high hydrophobic property and high durability is formed on an external surface of the printhead.
