  • Publication number: 20220084942
    Abstract: Methods for fabricating metallization stacks with one or more self-aligned staggered metal lines, and related semiconductor devices, are disclosed. Methods and devices are based on providing a spacer material conformal to bottom metal lines of a first layer of a metallization stack. By carefully designing parameters of the deposition process, the spacer material may be deposited in such a manner that, for each pair of adjacent bottom metal lines of the first layer, an opening in the spacer material is formed in a layer above the bottom metal lines (i.e., in the second layer of the metallization stack), the opening being substantially equidistant to the adjacent bottom metal lines of the first layer. Top metal lines are formed by filling the openings with an electrically conductive material, resulting in the top metal lines being self-aligned and staggered with respect to the bottom metal lines.

  • Patent number: 11264325
    Abstract: Integrated circuit (IC) structures, computing devices, and related methods are disclosed. An IC structure includes an interlayer dielectric (ILD), an interconnect, and a liner material separating the interconnect from the ILD. The interconnect includes a first end extending to or into the ILD and a second end opposite the first end. A second portion of the interconnect extending from the second end to a first portion of the interconnect proximate to the first end does not include the liner material thereon. A method of manufacturing an IC structure includes removing an ILD from between interconnects, applying a conformal hermetic liner, applying a carbon hard mask (CHM) between the interconnects, removing a portion of the CHM, removing the conformal hermetic liner to a remaining CHM, and removing the exposed portion of the liner material to the remaining CHM to expose the second portion of the interconnects.

  • Publication number: 20220051896
    Abstract: Techniques for selectively removing a metal or conductive material during processing of a semiconductor die for high-voltage applications are provided. In some embodiments, the techniques treat a metallized semiconductor die to transfer a feature from a patterned photoresist layer deposited on the metallized semiconductor die. In addition, the patterned metallized semiconductor die can be subjected to an etch process to remove an amount of metal according to the feature in the pattern, resulting in a treated metallized semiconductor die that defines an opening adjacent to at least a pair of neighboring metal interconnects in the die. The treated metallized semiconductor die can be further treated to backfill the opening with a dielectric material, resulting in a metallized semiconductor die having a backfilled dielectric member.
