    摘要: A thermal inkjet printhead with bubble forming heater elements formed from a material with a nanocrystalline composite structure. Nanocrystalline composite films can be superhard and can facilitate removal of the SiC and Ta anti-cavitation wear coatings. Improved oxidation resistance can also be achieved with some nanocrystalline composites, facilitating removal of the Si3N4 oxidation prevention coating. By removing or reducing the protective coatings, the heater element requires much less energy to form a bubble in the ink. A further benefit is improved crack resistance, which can extend the lifetime of uncoated heaters.

    摘要: An ink-jet printhead includes a substrate on which an ink chamber is formed, and a nozzle plate to cover the ink chamber, having a nozzle through which ink droplets are ejected from the ink chamber, and formed of a stack of a multi-layer insulating layer. The ink-jet printhead also includes a heater buried in the nozzle plate to surround the nozzle, an interconnection layer buried in the nozzle plate to electrically connect to the heater, and a coating layer formed of photoresist on the nozzle plate and having a through hole-type droplet guide connected to the nozzle of the nozzle plate. The droplet guide is formed through the coating layer, which has a sufficient thickness, and enables a meniscus of ink to be rapidly restored and stabilized, and ink droplets to be ejected at a high speed and high frequency. Also, the ink-jet printhead has improved resistance to abrasion and chemicals.
