摘要： PURPOSE: A bubble jet type ink jet print head and a method for fabricating same are provided to prevent ink from flowing back into a manifold by forming a vertical ink channel at a peripheral edge of an ink chamber having a semi-spherical shape. CONSTITUTION: A bubble jet type ink jet print head includes a plurality of ink exhaust sections, which is arranged on an ink feeding manifold(112) in two lines. Bonding pads, to which wires are bonded, are electrically connected to the ink exhaust sections. The bonding pads are arranged at both sides of the ink exhaust sections. The ink feeding manifold is connected to an ink storing container. An ink chamber(114) is formed on an upper surface of a substrate(110) of the ink exhaust section and the ink feeding manifold(112) is formed at the bottom surface of the substrate. A nozzle plate(120) having a nozzle(122) is stacked on the substrate(110). The nozzle plate(120) forms an upper wall of the ink chamber(114).

摘要： A bubble-jet type ink-jet printhead, and a manufacturing method thereof are provided. The printhead includes a substrate integrally having an ink supply manifold (102), an ink chamber (200), and an ink channel (106), a nozzle plate (110) having a nozzle (160), a heater (120), and an electrode (140) for applying current to the heater. In particular, the ink chamber is formed in a substantially hemispherical shape on a surface of the substrate, a manifold is formed from its bottom side toward the ink chamber, and the ink channel linking the manifold and the ink chamber is formed at the bottom of the ink chamber. This simplifies the manufacturing process and facilitates high integration and high volume production. Furthermore, a doughnut-shaped bubble is formed to eject ink in the printhead, thereby preventing a back flow of ink as well as formation of satellite droplets which may degrade image resolution.
