Abstract:
A method for manufacturing an ink-jet printhead having a hemispherical chamber, comprising:forming a ring-shaped groove for forming a nozzle guide at a surface of a substrate; forming a nozzle plate and a nozzle guide having a multi-layered structure and including a thermally conductive layer formed at the surface of the substrate; forming a heater having an interior diameter and an exterior diameter on the nozzle plate; forming a manifold for supplying ink by etching the substrate; forming an electrode on the nozzle plate to be electrically connected to the heater; forming a nozzle by etching the nozzle plate within the interior diameter of the heater to have a diameter nearly equal to the diameter of the nozzle guide; forming an ink chamber in a substantially hemispherical shape by etching the substrate exposed through the nozzle; and forming an ink channel for supplying ink from the manifold to the ink chamber by etching the substrate.
