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 a manifold and an ink channel to supply ink, a nozzle plate formed on the substrate, a chamber formed between the substrate and the nozzle plate and extending toward the substrate and the nozzle plate, an electrode formed at an interface between the substrate and the nozzle plate and around the chamber, and a heater having both ends extending in contact with the electrode to be suspended on the chamber in direct contact with the ink and to generate bubbles from both surfaces thereof. The inkjet printer head is capable of improving manufacturing process efficiency by omitting a process of separately forming a heater passivation layer, operating the heater at low electric power by omitting the heater passivation layer, improving integrity of a nozzle by lowering a working voltage, and improving reliability in manufacturing processes by locating the suspended heater to be in parallel with the substrate and the electrode.
