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 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 applying current to the heater are formed between the passivation layers. An epoxy nozzle layer is formed of a thermally conductive epoxy to cover the passivation layers. The epoxy nozzle layer is formed with a nozzle connected to the ink chamber.
