    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 inkjet print head and method of fabricating the same. The inkjet print head includes: a substrate having an ink-feed hole, an interlayer dielectric layer formed around the ink-feed hole on the substrate, at least one metal layer formed on the interlayer dielectric layer, and an anti-moisture part formed between the ink-feed hole and the at least one metal layer to prevent ink moisture in the ink-feed hole from contacting the at least one metal layer. The inkjet print head and the method of fabricating the same are capable of preventing problems such as de-lamination between layers, electrical short-circuit, circuit malfunction, and corrosion of a metal interconnection layer, since it is possible to prevent penetration of ink moisture from layers having absorbent characteristics into the metal interconnection layer, a logic region, or a pressure driving part. Therefore, it is possible to improve the lifespan and reliability of the inkjet print head as well as to increase productivity and reduce manufacturing cost by increasing yield.

    摘要： An inkjet printhead and a method of manufacturing the same. In the inkjet printhead, a substrate includes an ink chamber formed in a top surface to contain ink to be ejected, an ink feedhole formed in a bottom surface to supply the ink to the ink chamber, and a restrictor formed between the ink chamber and the ink feedhole to connect the ink chamber and the ink feedhole. A plurality of passivation layers are formed on the substrate. A heater and a conductor to apply a current to the heater are formed between the passivation layers. A heat transfer layer is formed on the passivation layers in a predetermined shape. An epoxy nozzle layer is formed to cover the passivation layers and the heat transfer layer. The epoxy nozzle layer is formed with a nozzle that is connected to the ink chamber.

    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.
