    • An ink jet printhead is disclosed which has improved printhead cooling thereby improving operating efficiency. The printhead is constructed so that the manifold bringing ink from an ink reservoir into an ink inlet to the printer directly contacts the thermally conductive surface of the substrate in which the heater elements are formed- The cooler ink removes some of the accumulated heat from the heater substrate and is subsequently ejected. In one embodiment the printhead comprises an upper channel substrate which is bonded to a lower heater substrate which is formed with a ledge which extends past the rear face of the channel substrate. The channel substrate has an ink inlet formed into its rear face and adjacent to an extended portion of the heater silicon surface. An ink reservoir brings ink to the printhead via an ink manifold which is sealed against the exposed silicon surface and against the side of the ink inlet. In a second embodiment, the formation of an ink inlet at the rear face enables the construction of a compact multicolor sideshooting printhead with 2 rows of nozzles.
    • 公开了一种喷墨打印头,其具有改进的打印头冷却,从而提高了操作效率。 打印头被构造成使得将墨水从墨水储存器插入到打印机的墨水入口中的歧管直接接触形成加热器元件的基板的导热表面。较冷的墨水从加热器中去除一些积聚的热量 底物并随后喷射。 在一个实施例中,打印头包括上通道基板,其被接合到下加热器基板,下加热器基板形成有延伸经过通道基板的后表面的凸缘。 通道基板具有形成在其后表面中并与加热器硅表面的延伸部分相邻的墨入口。 墨水储存器通过经由暴露的硅表面和墨水入口的侧面密封的墨水歧管向打印头提供墨水。 在第二实施例中,在后面形成墨水入口使得能够构造具有2排喷嘴的紧凑型多色侧面打印头。

    • The new heater element design has a pit layer which protects the overglaze passivation layer, PSG step region, portions of the Ta layer and dielectric isolation layer and junctions or regions susceptible to the cavitational pressures. Further, the inner walls of the pit layer define the effective heater area and the dopant lines define the actual heater area. In alternative embodiments, the dopant lines define the actual and effective heater areas, and an inner wall and a dopant line define the actual and effective heater areas. Further, when the new heater element designs are incorporated into printheads having full pit channel geometry and open pit channel geometry, the operating lifetime of the printhead is extended because the added protection of the pit layer prevents: 1) passivation damage and cavitational damages of the heater elements; and 2) degradation of heater robustness, hot spot formations and heater failures well into the 109 pulse range. The printhead incorporating the new heater element design can be incorporated into drop-on-demand printing systems of a carriage type or a full width type.
    • 新的加热器元件设计具有凹坑层,其保护釉面钝化层,PSG阶梯区域,Ta层和电介质隔离层的部分以及对空穴压力敏感的结或区域。 此外,凹坑层的内壁限定有效的加热器面积,并且掺杂剂线限定实际的加热器面积。 在替代实施例中,掺杂剂线限定实际和有效的加热器区域,并且内壁和掺杂剂线限定实际和有效的加热器区域。 此外,当新的加热器元件设计结合到具有全坑通道几何形状和露天通道几何形状的打印头中时,打印头的工作寿命延长,因为凹坑层的附加保护防止:1)钝化损伤和空穴损伤 加热元件; 和2)加热器鲁棒性,热点形成和加热器故障的恶化达到109脉冲范围。 包含新的加热器元件设计的打印头可以结合到托架型或全宽型的按需按需打印系统中。
