    摘要： A heat transfer type ink-jet print head and a method of fabricating the same. A method of fabricating an ink-jet print head includes sequentially laminating a heat generation layer and an electrode layer on a substrate, laminating a protective layer on the top surfaces of the electrode layer and the heat generation layer by sequentially laminating a first protective layer and a second protective layer on the top surfaces of the electrode layer and the heat generation layer, and laminating an ink chamber barrier and a nozzle plate on the top surface of the protective layer to form an ink chamber to prevent defects such as “pin-holes” from being generated during the formation of the first protective layer.

    摘要： An ink-jet print head and a method of making the same comprising the steps of sequentially laminating a heating layer and an electric conductive layer on a substrate, patterning the electric conductive layer to expose a predetermined area of the top surface of the heating layer, forming a protective layer on the top surfaces of the electric conductive layer and exposed heating layer, and laminating an ink chamber barrier and a nozzle plate on the top surface of the protective layer, thereby forming an ink chamber. The protective layer is provided by forming a cavitation layer by alternately laminating at least two types of thin film layers of different materials over the exposed heating layer and the electric conductive layer to resist fractures and oxidization resulting from use.

    摘要： A method of fabricating a high efficiency inkjet print head includes forming an oxide film on a surface of a substrate, sequentially forming and patterning a heater layer and a wiring layer on the oxide film, forming a passivation layer on the heater layer and the wiring layer and patterning the passivation layer so that a heater is exposed, etching the substrate to form restrictors at both sides of the heater, forming a chamber layer on the passivation layer, forming a sacrificial layer on the chamber layer and polishing the sacrificial layer, forming a nozzle layer on the chamber layer, forming an ink-feed hole at a bottom surface of the substrate, and removing the sacrificial layer. The inkjet print head is capable of reducing energy consumption by fabricating a heater having high efficiency, and capable of maintaining good heating characteristics since an original temperature of the inkjet print head is rapidly recovered after the heater is instantly heated and electric current is not supplied. In addition, since the heater is mounted on the substrate, the inkjet print head can maintain structural integrity, and since the heater is formed in a planar shape without bent portions, the heater can be formed to a uniform thickness.

    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.
