    • 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.
    • 本发明是一种流体喷射装置,例如打印头,其具有基底,其具有与孔层相匹配的第一表面,优选地通过一叠薄膜层。 孔口层限定与孔口或喷嘴连接的流体室。 基板具有具有截头棱锥结构的第二表面; 多面体或三角形脊形,限定通过基底的开口到流体室。 衬底还具有优选地设置在薄膜层堆叠中作为电阻器的喷射元件。 当能量从喷射元件转移到流体室中的流体时,流体从孔口排出。 流体喷射装置可以具有一个或多个流体室和一个或多个截头圆锥体,其截断的多面体,截头锥体,截头圆锥形或截头三角形横截面脊结构限定从衬底的第二表面到流体的开口 房间。
