    摘要： An ink-jet printhead includes a substrate on which an ink chamber is formed, and a nozzle plate to cover the ink chamber, having a nozzle through which ink droplets are ejected from the ink chamber, and formed of a stack of a multi-layer insulating layer. The ink-jet printhead also includes a heater buried in the nozzle plate to surround the nozzle, an interconnection layer buried in the nozzle plate to electrically connect to the heater, and a coating layer formed of photoresist on the nozzle plate and having a through hole-type droplet guide connected to the nozzle of the nozzle plate. The droplet guide is formed through the coating layer, which has a sufficient thickness, and enables a meniscus of ink to be rapidly restored and stabilized, and ink droplets to be ejected at a high speed and high frequency. Also, the ink-jet printhead has improved resistance to abrasion and chemicals.

    摘要： An ink-jet printhead and a manufacturing method thereof include a substrate on which an ink chamber having a predetermined volume is formed, a passage for supplying ink to the ink chamber which is formed on a bottom of the ink chamber, a nozzle plate which includes a nozzle corresponding to a center of the ink chamber and at least two insulating layers formed on the substrate, a bubble guide formed inside the nozzle plate and extending from the nozzle into the ink chamber, and a heater which surrounds the nozzle and is disposed between the two insulating layers. A hydrophobic coating layer is formed on a surface of a uppermost layer of the nozzle plate, and a droplet ejecting portion that has a diameter smaller than that of the nozzle of the nozzle plate and is disposed on the same axis as the nozzle, is formed in the hydrophobic coating layer. The nozzle plate is prevented from becoming wet due to ink, stability of an ink spray and a consecutive spray performance are improved, and thus a printing quality and a printing performance of the ink-jet printhead are generally improved.

    摘要： A bubble-jet type inkjet printhead is disclosed, wherein a manifold for supplying ink, an ink chamber having a substantially hemispherical shape and filled with ink to be ejected, and an ink channel for supplying ink from the manifold to the ink chamber, are incorporated in a substrate. A nozzle plate having a nozzle, through which ink is ejected at the center of the ink chamber, is formed on the substrate. A heater is provided on the nozzle plate and surrounding the nozzle, and electrodes are provided on the nozzle plate and electrically connected to the heater to supply pulse current to the heater. An anti-wetting coating including a perfluorinated alkene compound on at least a surface around the nozzle is formed on an exposed surface of the printhead. Preferably, the anti-wetting coating is deposited by RF glow discharge and can be removed by O2 plasma.
