    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.
