    摘要： A method of manufacturing an inkjet printhead includes forming a first photoresist layer on a substrate having ink ejection devices disposed thereon by coating the substrate with a first negative photoresist, exposing the first photoresist layer through a first photomask formed that defines a pattern of ink chambers, forming a second photoresist layer on the first photoresist layer by coating the first photoresist layer with a second negative photoresist, exposing the second photoresist layer through a second photomask that defines a pattern of nozzles, forming a nozzle layer having the nozzles by developing the second photoresist layer, forming the ink chambers by developing the first photoresist layer through the nozzles, and forming an ink supply path by etching a lower surface of the substrate. Thus, an inkjet printhead and a method of manufacturing the same are provided, where the manufacturing process is simple, and it is easy to control ink chambers and an ink flow path to have desired sizes and/or uniform sizes.

    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 operations of 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, wherein defects such as “pin-holes” generated during the formation of the first protective layer are removed by applying a plasma on the first protective layer, and the second protective layer is laminated on the top surface of the first protective layer after any defect produced when laminating the first protective layer is removed.
