Ink-jet printhead and method of manufacturing the same
An ink-jet printhead and a method of manufacturing the ink-jet printhead include forming an insulating layer on a surface of a substrate, forming a metallic thin layer on the insulating layer, pattering the metallic thin layer through dry etching to form a plurality of pairs of conductors corresponding to a plurality of heaters to be formed in a subsequent operation, forming a resistant material layer on the substrate, patterning the resistant material layer through dry etching to form the heaters corresponding to the conductors, forming a nonconductive heat transfer layer on the substrate so as to cover the heaters and the conductors, forming a passage plate providing an ink chamber, in which each of the heaters are placed, on the substrate, and forming a nozzle plate having a nozzle corresponding to each ink chamber on the passage plate.
