    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: An inkjet printer head includes a substrate having an ink-feed hole to supply ink stored in a cartridge to an ink chamber and a restrictor in fluid communication with the ink chamber, an oxide layer formed on the substrate, a heater disposed on the oxide layer above the restrictor and having fixed parts disposed on the oxide layer, slopes extending upward and away from the restrictor at an incline, and a parallel part extending between the slopes parallel to the substrate, a lead formed to be in electrical contact with the heater, a chamber layer formed to cover the lead and to define the ink chamber, and a nozzle layer formed on the chamber layer and having a nozzle. In the inkjet printer head, the lifespan of the heater may be extended since the heater is supported by the slopes, which function as a shock absorbing member when ink supply pressure or cavitation force is applied to a surface of the heater. In addition, since the heater does not have a right angle structure, the heater may be formed to have a uniform thickness even when a thin layer used for the heater is formed by a deposition method.

    摘要: An inkjet printer head includes a substrate having a manifold and an ink channel to supply ink, a nozzle plate formed on the substrate, a chamber formed between the substrate and the nozzle plate and extending toward the substrate and the nozzle plate, an electrode formed at an interface between the substrate and the nozzle plate and around the chamber, and a heater having both ends extending in contact with the electrode to be suspended on the chamber in direct contact with the ink and to generate bubbles from both surfaces thereof. The inkjet printer head is capable of improving manufacturing process efficiency by omitting a process of separately forming a heater passivation layer, operating the heater at low electric power by omitting the heater passivation layer, improving integrity of a nozzle by lowering a working voltage, and improving reliability in manufacturing processes by locating the suspended heater to be in parallel with the substrate and the electrode.

    摘要: An ink-jet print head preventing thermal accumulation on a nozzle plate includes a substrate, a channel formed in the substrate to supply ink, a nozzle plate connected to the substrate and including a nozzle corresponding to the channel, a heat element formed in the nozzle plate to surround the nozzle, a thermal conduction layer formed on an upper side of the heat element formed between the thermal conduction layer and the heat element, and a thermal shunt spaced-apart from the heat element by a predetermined distance not to overlap the heat element in a direction parallel to the nozzle plate and connecting the thermal conduction layer to the substrate. Redundant heat generated from the heat element is not accumulated on a membrane of the nozzle plate but is rapidly absorbed into an inorganic thermal conduction layer formed in the membrane and is transferred to the bulk silicon substrate through a metallic thermal bridge, such as the thermal shunt.
