Abstract: A bubble-jet type ink jet printhead and manufacturing method thereof are provided. In the printhead, a manifold for supplying ink and a concave ink chamber is integrated with a substrate by being recessed from the same surface of the substrate, and a nozzle palate on the substrate in which a nozzle is formed and a round-shaped heater surrounding the nozzle are integrated without a complex process such as bonding. Thus, this simplifies the manufacturing procedure and facilitates high volume production. Furthermore, the round-shaped heater forms a doughnut-shaped bubble to eject ink, thereby preventing a back flow of ink as well as formation of satellite droplets which may degrade image resolution.

Abstract: PURPOSE: Print head structure of an inkjet printer is provided not to have a process for forming a manifold and to prevent the mechanical strength from getting weak by a manifold, by not forming a manifold passing through a substrate, and using a space between two plates as a manifold. CONSTITUTION: Plural ink discharge ports are formed on two substrates(120a,120b). Heaters(125) for generating bubbles are mounted on the surface of each substrate. Walls(127) are formed at both left and right sides of the heaters to form ink chambers respectively. Bonding pads(126,126') are connected to the tip of wires(134,134') for feeding an electric signal. Each ink discharge ports are driven and controlled according to the electric signal. The bonding pads and the wire are made by metals such as Al at the same time. The substrates of a print head have no additional manifold. In the print head, a manifold is not formed but a space between the substrates is used as a manifold. Thereby, an additional process for forming a manifold is not required. In addition, the mechanical strength of the print head is kept regular.
