| Summary: | This invention relates generally to an integrated thin-film drive head for thermal ink-jet printing and more particularly, to a drive head wherein the driver transistor, the resistor and the interconnect are comprised of the same thin-film layer.
A thin-film ink-jet drive head provides a MOSTFT (metal oxide semiconductor thin-film transistor) transistor, a resistor and the interconnect between the two electrical components, all comprised of the same, multi-functional thin-film layer. Differing portions of the multi-functional thin-film layer function as (1) heating resistors to propel ink droplets from the printhead (2) ink MOSTFT transistors to selectively drive (fire) the resistors, and (3) direct conductive pathways between the drive transistors and the resistors. |
