    摘要: A method of forming a damascene wire. The method including: forming a mask layer on a top surface of a dielectric layer; forming an opening in the mask layer; forming a trench in the dielectric layer where the dielectric layer is not protected by the mask layer; recessing the sidewalls of the trench under the mask layer; forming a conformal conductive liner on all exposed surface of the trench and the mask layer; filling the trench with a core electrical conductor; removing portions of the conductive liner extending above the top surface of the dielectric layer and removing the mask layer; and forming a conductive cap on a top surface of the core conductor.

    摘要: A structure. The structure includes: a core electrical conductor having a top surface, an opposite bottom surface and sides between the top and bottom surfaces; an electrically conductive liner in direct physical contact with and covering the bottom surface and the sides of the core electrical conductor, embedded portions of the electrically conductive liner in direct physical contact with and extending over the core electrical conductor in regions of the core electrical conductor adjacent to both the top surface and the sides of the core electrical conductor; and an electrically conductive cap in direct physical contact with the top surface of the core electrical conductor that is exposed between the embedded portions of the electrically conductive liner.
