Abstract
A process for fabricating a thin-film structure using a transparent substrate is disclosed. A first structure, such as a ring, is formed of a dielectric material on a conductive material layer. The conductive material is partially removed, such as within the center of the ring structure. A photoresist material pillar is formed to fill the center of the ring structure, protruding above the ring structure rim. Such structures are useful as mandrel structures in the forming of precision components, such as nozzle plates, mesh ink filter screens, and the like, for ink-jet pens.
