    • This application discloses a novel thermal ink jet printhead and related integrated pulse driver circuit useful in thermal ink jet printers. This combined printhead and pulse drive integrated circuit includes a first level of metalization comprising a refractory metal which is patterned to define the lateral dimension of the printhead resistor. A passivation layer or layers are deposited atop this first level of metalization and patterned to have an opening or openings therein for receiving a second level of metalization. This second level of metalization such as aluminum may then be used for electrically interconnecting the printhead resistors to MOSFET drivers and the like which have been fabricated in the same silicon substrate which provides support for the printhead resistors. Thus, this "on-chip" driver construction enables these pulse driver transistors to be moved from external electronic circuitry to the printhead substrate.

    • An inkjet printhead structure comprises novel resistor circuitry that is fabricated on two different substrate layers. The dual layer circuitry reduces the required substrate surface area and printhead shelf length to increase the printer operating frequency and print density. In one embodiment of the invention, heating resistors are spread out over portions of the substrate surface area and conductors are attached to opposite ends of the heater resistors in a novel configuration. To simplify routing, the circuitry is configured so that multiple heater resistors are coupled to the same conductor return path located on a second conductive layer. In a second embodiment of the invention, the heater resistors are dimensioned in the shape of a trapezoid to provide uniform heating. Alternative resistor shapes are then introduced to provide consistent heat dissipation for variances in resistor/conductor sheet resistance.
    • 喷墨打印头结构包括制造在两个不同基底层上的新型电阻电路。 双层电路减少了所需的衬底表面积和打印头搁架长度,以增加打印机的工作频率和打印密度。 在本发明的一个实施例中,加热电阻器分散在衬底表面区域的一部分上,并且导体以新颖的结构附接到加热器电阻器的相对端。 为了简化路由,电路被配置为使得多个加热电阻器耦合到位于第二导电层上的相同的导体返回路径。 在本发明的第二实施例中,加热电阻的尺寸设计为梯形,以提供均匀的加热。 然后引入替代的电阻器形状,以提供电阻/导体薄层电阻变化的一致的散热。
