Abstract
A method of fabricating an ink jet head and an ink jet head fabricated thereby. The method includes preparing a substrate having a flow path region, a flow path structure region to define the flow path region, and a pad region disposed at edge portions of the substrate. At least one pressure-generating element to eject ink is formed on the substrate of the flow path region. An inserting material layer is formed on an entire surface of the substrate having the at least one pressure-generating element. The inserting material layer is patterned to form an inserting layer on the flow path structure region. A mold layer is formed on the substrate having the inserting layer to cover the flow path region. Next, a nozzle material layer is formed on the entire surface of the substrate having the inserting layer and the mold layer. The nozzle material layer is patterned to form a nozzle layer covering the inserting layer and the mold layer and having at least one nozzle passing through the nozzle material layer on the mold layer to correspond to the at least one pressure-generating element.
