Large thermal ink jet nozzle array printhead |
摘要 |
<p>This present invention is embodied in a large array printhead (300) having a large array of thin-film ink drop generators formed on a single monolithic substrate (310). The large array printhead (300) includes a multiplexing device (315) to reduce parasitic resistance and the number of incoming leads. In a preferred embodiment, the substrate (310) is initially patterned and etched and the multiplexing device (315) is attached to the substrate (310) at a later time. The present invention also includes methods of fabricating a plurality of large array printhead embodiments using a single monolithic substrate (1000) made of a suitable material, preferably having a low coefficient of thermal expansion. <IMAGE></p> |
