ABSTRACT:
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.
