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.

摘要： A bubble-jet type ink-jet printhead has a structure in which a base plate, a barrier wall, and a nozzle plate are stacked. The base plate includes a substrate on which a recess is formed to a predetermined depth, an adiabatic layer formed on the substrate, a heater which is formed on the adiabatic layer and generates a thermal energy, and a passivation layer which is formed on the heater and passivates the heater. The barrier wall is stacked on the base plate, defines an ink chamber, which is disposed on the recess and has a recessed bottom surface, and defines an ink passage which communicates with the ink chamber. The nozzle plate is stacked on the barrier wall, has nozzles through which ink is ejected, and is formed at a location corresponding to a center of the ink chamber. Since a height of the barrier wall surrounding the ink chamber is reduced by the recess, delamination caused by ink soaked into the barrier wall can be prevented, and print performances such as a traveling property in a straight direction of ink droplets and ejection velocity of ink droplets, are improved.

摘要： An ink-jet print head preventing thermal accumulation on a nozzle plate includes a substrate, a channel formed in the substrate to supply ink, a nozzle plate connected to the substrate and including a nozzle corresponding to the channel, a heat element formed in the nozzle plate to surround the nozzle, a thermal conduction layer formed on an upper side of the heat element formed between the thermal conduction layer and the heat element, and a thermal shunt spaced-apart from the heat element by a predetermined distance not to overlap the heat element in a direction parallel to the nozzle plate and connecting the thermal conduction layer to the substrate. Redundant heat generated from the heat element is not accumulated on a membrane of the nozzle plate but is rapidly absorbed into an inorganic thermal conduction layer formed in the membrane and is transferred to the bulk silicon substrate through a metallic thermal bridge, such as the thermal shunt.

摘要： An ink-jet printhead and a manufacturing method thereof include a substrate on which a space portion is formed, a passage plate installed on the substrate in which an ink chamber is formed to store ink, a nozzle plate installed at a top surface of the passage plate in which a nozzle is formed to eject the ink, and a vibration plate disposed between the substrate and the passage plate to generate a pressure for ejecting the ink by changing a volume of the ink chamber. The vibration plate includes a base layer formed at a top surface of the substrate so as to cover at least a part of the space portion, a thin film shape memory alloy layer which contacts the ink contained in the ink chamber and varies according to a temperature variation, a heating element disposed between the base layer and the thin film shape memory alloy to generate heat, and an insulating layer disposed between the heating element and the thin film shape memory alloy layer and transfers the heat generated by the heating element to the thin film shape memory alloy layer. Due to a stable temperature coefficient of resistance (TCR) of the heating element, a height and a width of a voltage supplied to the heat element can be easily controlled, and thus power of the vibration plate can be precisely controlled, thereby having a predetermined image quality, and the heating element does not contact directly the ink, thereby realizing stability of the ink-jet printhead.

摘要： A head of an inkjet printer is formed by bonding of a heater substrate and a nozzle plate. In order to bond the heater substrate where a heater thin film and a protecting film are vapor-deposited, and the nozzle plate where a nozzle is formed, an intermediate layer is formed by forming a thin film of glass on the heater substrate by vapor-depositing, and the nozzle plate is installed on the heater substrate. SiO2 is formed at an interface between the nozzle plate and the heater thin film due to heating and application of an electric field, and thus the nozzle plate and the heater substrate are bonded with an electrostatic force of SiO2. The nozzle plate and the heater substrate are bonded by using the intermediate layer made of the thin film of glass instead of a general polymer as the bonding layer, thereby preventing swelling of the polymer and isolation of layers of the head occurring due to ink penetration into interfaces of the layers. Moreover, a bonding process is performed in wafer units to improve mass productivity.

摘要： An inkjet printhead and a manufacturing method thereof. The inkjet printhead includes a substrate, a substantially cylindrical ink chamber storing ink and formed in an upper portion of the substrate, and a manifold supplying ink to the ink chamber in a bottom portion of the substrate, a channel-forming layer disposed between the ink chamber and the manifold and having an ink channel communicating between the ink chamber and the manifold, a nozzle plate stacked on the substrate and having a nozzle at a location corresponding to the central part of the ink chamber, a heater formed to surround the nozzle of the nozzle plate, and electrodes electrically connected to the heater to supply current to the heater. Therefore, the quantity of ink stored in an ink chamber can be increased. Also, when bubbles grow, the cylindrical ink chamber confines an ink flow area to ink ejectors, thereby reducing a back flow of the ink. Further, the quantity of ink supplied to the ink chamber can be adjusted by varying the number of ink channels formed in the channel-forming layer, thereby improving frequency characteristics of the inkjet printhead.
