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： A method of fabricating an ink jet head having a metal chamber layer includes preparing a substrate having pressure-generating elements to generate pressure to eject ink ejection. The metal chamber layer to define sidewalls of an ink flow path is then formed on the substrate. A sacrificial layer is formed to fill a region where the ink flow path is to be formed between the sidewalls defined by the metal chamber layer. A nozzle layer having nozzles corresponding to the pressure-generating elements is formed on the metal chamber layer and the sacrificial layer.

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 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.
