摘要： A method of manufacturing a monolithic inkjet printhead wherein the uniformity of the ink flow path is maintained by ensuring that the flow path forming layer and the nozzle layer are completely adhered to each other. The method includes forming a heater and electrode on a substrate, coating a negative photoresist on the substrate, and patterning the photoresist using a photolithography process to form an flow path forming layer that defines an ink flow path. The method further comprises steps for then forming a sacrificial layer so as to cover the flow path forming layer and then flattening upper surfaces of the flow path forming layer and the sacrificial layer using a chemical mechanical polishing (CMP) process such that when a nozzle layer is then formed, the flow path forming layer and the nozzle layer are completely adhered to each other.

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.
