    摘要： An ink-jet printhead and a method for manufacturing the same are provided. The ink-jet printhead includes a substrate (100) on which an ink chamber (106) filled with ink to be ejected is formed on a surface of the substrate, a manifold (102) for supplying ink to the ink chamber is formed on a rear surface of the substrate, and an ink passage (105) for connecting the ink chamber to the manifold is formed parallel to the surface of the substrate, and a nozzle plate (114) stacked on the substrate, in which a nozzle (104) through which ink is ejected from the ink chamber is formed, a heater (108) and an electrode (112) electrically connected to the heater, for applying current to the heater, are arranged.

    摘要： A bubble-jet type ink-jet printhead is provided. The bubble-jet type ink-jet printhead includes a substrate 100, a nozzle plate 101, a wall 102, and a heater 103. The heater 103 is interposed between the substrate 100 and the nozzle plate 101 to divide an ink chamber filled with ink into a main ink chamber 106 and a secondary ink chamber 107, thereby generating a main bubble and a secondary bubble. The printhead further includes an ink channel 110 for introducing ink into the secondary ink chamber 107 and then supplying the ink to the main ink chamber 106. Accordingly, the printhead consumes less energy, prevents a backflow of ink, and operates at increased speed.
