    摘要: Inkjet printheads capable of printing smaller and larger drop-weight quantities of ink, and methods of manufacturing the inkjet printheads, are disclosed. The inkjet printhead includes a substrate. One or more portions of the substrate may be etched such that the substrate might have different thicknesses. A thin-film layer is connected to the substrate and contains independently addressable ink-energizing elements, preferably resistors. An orifice layer having a substantially planar exterior surface is applied directly to the thin-film layer. Consequently, the thickness of the orifice layer varies with the thickness of the substrate. At least one firing chamber is defined in each portion of the orifice layer with a different thickness and, preferably, different-sized resistors. Alternatively, the orifice layer has a substantially uniform thickness. In order to achieve the multiple drop-weight capability of the present invention, firing chambers of different volumes are provided. In this embodiment, firing chambers that are to provide a larger drop-weight preferably have a more powerful ink-energizing element and are laterally offset from the firing chamber nozzle aperture. Other firing chambers that are to provide a small drop-weight preferably have a less powerful ink-energizing element and are aligned with the firing chamber nozzle aperture. Thus, the present invention provides inkjet printheads capable of printing various drop-weight quantities of ink.

    摘要: The invention is a fluid ejection device, such as a printhead, that has a substrate with a first surface mating to an orifice layer, preferably through a stack of thin-film layers. The orifice layer defines a fluid chamber interfacing to an orifice opening or nozzle. The substrate has a second surface having a truncated pyramidal structure; either polyhedral or triangular ridge shaped defining an opening through the substrate to the fluid chamber. The substrate further has an ejection element, preferably disposed as a resistor in the stack of thin-film layers. When energy is transferred from the ejection element to the fluid in the fluid chamber, fluid is ejected from the orifice opening. The fluid ejection device may have one or a plurality of fluid chambers and one or a plurality of frustums of a truncated polyhedral, truncated pyramidal, truncated conical or truncated triangular cross-sectional ridge structures defining openings from the second surface of the substrate to the fluid chambers.
