摘要： An inkjet printer head and method of fabricating the same includes a substrate having an ink-feed hole formed at a bottom surface of the substrate, a lower chamber formed at a top surface of the substrate, and a restrictor to fluid communicate between the ink-feed hole and the lower chamber, an oxide layer formed on the substrate, a heater formed on the oxide layer and disposed parallel to the surface of the substrate to cross the lower chamber, a lead electrically connected to the heater, and a nozzle layer disposed on the heater to configure an ink channel together with the lower chamber and having a nozzle at an upper portion of the nozzle layer. The inkjet printer head is capable of improving a thermal efficiency by heating the ink using both surfaces of the heater since the heater is disposed at a center of the ink chamber, and improving characteristics of the heater by making a current density and a current flow uniform since the heater is formed in a straight line without any bent or curved portion.

摘要： An inkjet printer head includes a substrate having an ink-feed hole to supply ink stored in a cartridge to an ink chamber and a restrictor in fluid communication with the ink chamber, an oxide layer formed on the substrate, a heater disposed on the oxide layer above the restrictor and having fixed parts disposed on the oxide layer, slopes extending upward and away from the restrictor at an incline, and a parallel part extending between the slopes parallel to the substrate, a lead formed to be in electrical contact with the heater, a chamber layer formed to cover the lead and to define the ink chamber, and a nozzle layer formed on the chamber layer and having a nozzle. In the inkjet printer head, the lifespan of the heater may be extended since the heater is supported by the slopes, which function as a shock absorbing member when ink supply pressure or cavitation force is applied to a surface of the heater. In addition, since the heater does not have a right angle structure, the heater may be formed to have a uniform thickness even when a thin layer used for the heater is formed by a deposition method.
