摘要： An inkjet print head with a high efficiency heater includes a substrate having an ink-feed hole extending therethrough to receive ink stored in a cartridge, a flow path layer to define an ink chamber in fluid communication with the ink-feed hole, a nozzle plate having a nozzle to discharge the ink from the ink chamber to an exterior, a heater located adjacent to an inner wall of the ink chamber and disposed in contact with the ink in the ink chamber, and a lead electrically connected to the heater. The heater increases thermal efficiency and maintains a stable structure. In addition, since the heater is disposed adjacent to the inner wall of the ink chamber, the heater is barely affected by the ink supply pressure or the cavitation force that results from ink bubbles shrinking.

摘要： A method of fabricating an ink jet head. The method includes preparing a substrate having first and second surfaces, the substrate being provided with a plurality of pressure-generating elements disposed on the first surface. A mask pattern having at least one opening is formed on the first surface on which the pressure-generating elements are disposed. The method further includes forming an ink-feed channel that extends through the substrate from the first surface by using the mask pattern as an etch mask. The method is capable of improving yield and reliability of the ink jet head since the shape and dimension of the ink-feed channel may be uniformly and reproducibly adjusted.

摘要： An ink jet head having a filtering member integrally formed with a substrate and method of fabricating the same are provided. The ink jet head includes a plurality of pressure-generating elements disposed on a substrate to generate pressure to provide ink ejection. An ink-feed passage extending through the substrate is disposed to be spaced apart from the pressure-generating elements. A manifold recessed from a top surface of the substrate by a predetermined depth and having a width defined by the ink-feed passage is disposed between the pressure-generating elements and the ink-feed passage. A plurality of filtering pillars is disposed on a bottom surface of the manifold to provide filter openings therebetween. The filtering pillars are integrally formed with the substrate. A flow path structure defining a flow path is disposed on the top surface of the substrate, wherein the flow path includes ink chambers that contain the pressure-generating elements therein, ink channels that open the ink chambers toward a direction of the manifold, and nozzles that are in fluid communication with the ink chambers.
