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： A method of fabricating a high efficiency inkjet print head includes forming an oxide film on a surface of a substrate, sequentially forming and patterning a heater layer and a wiring layer on the oxide film, forming a passivation layer on the heater layer and the wiring layer and patterning the passivation layer so that a heater is exposed, etching the substrate to form restrictors at both sides of the heater, forming a chamber layer on the passivation layer, forming a sacrificial layer on the chamber layer and polishing the sacrificial layer, forming a nozzle layer on the chamber layer, forming an ink-feed hole at a bottom surface of the substrate, and removing the sacrificial layer. The inkjet print head is capable of reducing energy consumption by fabricating a heater having high efficiency, and capable of maintaining good heating characteristics since an original temperature of the inkjet print head is rapidly recovered after the heater is instantly heated and electric current is not supplied. In addition, since the heater is mounted on the substrate, the inkjet print head can maintain structural integrity, and since the heater is formed in a planar shape without bent portions, the heater can be formed to a uniform thickness.
