    摘要： A thermally-driven ink-jet printhead includes a substrate having an ink chamber to be filled with ink to be ejected, a manifold for supplying ink, and an ink channel for providing flow communication therebetween. First and second sidewalls are formed to a predetermined depth from an upper surface of the substrate and define the ink chamber to have a substantially rectangular shape. A nozzle plate including a plurality of material layers is formed on the substrate. A nozzle passes through the nozzle plate and is in flow communication with the ink chamber. A heater is disposed between the nozzle and one of the first sidewalls above the ink chamber. A conductor is electrically connected to the heater. The conductor and the heater are disposed within the nozzle plate. A shifting feature moves cavitation points beyond an outer edge of the heater.
