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.
