Abstract:
1. A semiconductor construction, comprising: an electrically insulative material directly on a surface of a semiconductor substrate, the electrically insulative material consisting of one or more materials selected from the group consisting of silicon dioxide, borophosphoslicate glass, and phosphosilicate glass; an opening extending only partially into the electrically insulative material, the opening having a pair of vertically opposing sidewalls that each meet a bottom of the opening, the bottom of the opening extending across the width of the opening and being disposed above the surface of the semiconductor substrate; a metal liner directly contacting the electrically insulative material of sidewalls and bottom of the opening, the metal liner consisting of one or more transition metals combined with one or both of cobalt and ruthenium; and copper-containing material within the opening and directly against the metal liner.
