1. A method of fabricating an orifice plate for use in an ink jet printing system, comprising the steps of:

  • providing a substrate base;

    applying a controlled-release layer to a surface of the substrate base;

    adherently coating a conductive metal layer on the controlled-release layer;

    creating at least one dielectric peg on a portion of the conductive metal layer;

    applying a nozzle layer on the conductive metal layer wherein the nozzle layer partially covers the at least one dielectric peg;

    using photolithography to define a trench that covers the nozzles prior to formation of a second reinforcing layer;

    removing the controlled-release layer to separate the orifice plate from the substrate base;

    selectively etching the conductive metal layer from the nozzle layer to produce a completed multi-layer orifice plate.
