    Abstract: A method for fabricating a microelectronic layer. There is first provided a substrate. There is then formed over the substrate a target layer. There is then formed upon the target layer a patterned photoresist layer which defines a first aperture, where the first aperture has a first aperture width which exposes a first portion of the target layer. There is then reflowed thermally the patterned photoresist layer to form a reflowed patterned photoresist layer which defines a substantially straight sided second aperture. The second aperture has a second aperture width less than the first aperture width, and the second aperture thus exposes a second portion of the blanket target layer of areal dimension less than the first portion of the blanket target layer. Finally, there is then fabricated the target layer to form a fabricated target layer while employing the reflowed patterned photoresist layer as a mask layer. The method is useful insofar as it allows the target layer to be fabricated while avoiding the use of advanced microelectronic fabrication photolithographic tooling when forming the patterned photoresist layer.

    Abstract: A robust dual damascene process is disclosed where the substructure in a substrate is protected from damage caused by multiple etchings required in a damascene process by filling a contact or via hole opening with a protective material prior to the forming of the conductive line opening of the damascene structure having an etch-stop layer separating a lower and an upper dielectric layer. In the first embodiment, the protective material is partially removed from the hole opening reaching the substructure prior to the forming of the upper conductive line opening by etching. In the second embodiment, the protective material in the hole is removed at the same time the upper conductive line opening is formed by etching. In a third embodiment, the disclosed process is applied without the need of an etch-stop layer for the dual damascene process of this invention.
