    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.
