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 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.
