  • Method for making ink jet printheads
    Patent number: 6704996
    Abstract: The invention provides a method for reducing ink corrosion of exposed metal layers on a chip surface of a semiconductor chip for an ink jet printhead. The method includes depositing a protective layer in a plasma process to the chip surface, the protective layer being deposited adjacent ink ejectors so that the protective layer substantially circumscribes an ink via in the chip. A thick film layer is applied to the protective layer and chip, whereby the protective layer and thick film layer are sufficient to promote increased adhesion between the thick film layer and a nozzle plate attached to the thick film layer thereby substantially reducing a tendency for the nozzle plate and thick film layer to delaminate from one another during printhead manufacture or use and interrupting contact between ink and the exposed metal layers on the chip surface.
    Type: Grant
