    摘要： An inkjet printer head includes a substrate, an insulating layer having a groove and disposed on the substrate, a heating member having a concavely curved upper surface and disposed on an upper portion of the groove, an electrode to make contact with the heating member to apply electric current to the heating member, a chamber layer disposed on the heating member, and a nozzle layer having one or more nozzles and disposed on the chamber layer. According to the inkjet printer head, the heating member has a curved structure to increase a length of the heating member, so that resistance of the heating member can be increased. Thus, the heating member can stably operate regardless of current variation applied thereto, and the printing work can be performed.

    摘要： An inkjet print head and manufacturing method includes a substrate, an insulating layer formed on a surface of the substrate to have an electrode formation space, an electrode formed in the electrode formation space to be positioned on the same plane with the insulating layer, a heater formed on upper surfaces of the insulating layer and the electrode, and a passivation layer formed on the insulating layer and the heater. The heater is formed to be flat on the insulating layer and the electrodes, thereby reducing the thickness of the passivation layer. Further, copper having relatively high electric conductivity is used as a material of the electrodes, which apply current to the heater to generate heat, instead of aluminum, thereby increasing a degree of freedom in the thickness of the electrodes. Further, uniform current can be applied to the respective heaters at different positions in single firing and full firing of ink, thereby reducing entire input energy and also improving ink ejection stability and reliability of the inkjet print head.

    摘要： An inkjet print head including a substrate and a first film member stacked on the substrate to form an ink path, and a manufacturing method thereof. The first film member includes a path-defining layer made of a photosensitive material and formed with the ink path, and an adhesive layer made of a photosensitive material and used to stably bond the path-defining layer to the substrate. With this configuration, the path-defining layer and the adhesive layer can be simultaneously stacked on the substrate and also, can be patterned simultaneously.
