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.

摘要： A monolithic nozzle assembly formed with a mono-crystalline silicon substrate includes a damper for temporarily storing an incoming fluid, and a nozzle having a pyramidal portion and an outlet portion, the pyramidal portion for guiding the flow of the fluid from the damper toward the outlet portion and for increasing the pressure of the fluid, and the outlet portion through which the fluid is discharged, wherein the damper, and the pyramidal and outlet portions of the nozzle are aligned with each other and formed in the single mono-crystalline silicon substrate by continuous processes. The monolithic nozzle assembly can be formed with a single (100) mono-crystalline silicon wafer. Compared with a complicated nozzle assembly formed using a great number of silicon wafers and plates, the configuration of the monolithic nozzle assembly is simple, and can be manufactured on a mass production scale by semiconductor manufacturing processes.
