Abstract:
1. A method of forming an electrically conductive line, comprising: providing a longitudinally elongated trench within a substrate, the trench being laterally wider at a first longitudinal location in comparison to a second longitudinal location; depositing a first conductive material to fill the trench at the second location and to less than fill and to line the trench at the first location; depositing a second conductive material within the trench at the first location in electrical connection with the first conductive material, the first conductive material lining sidewalls of the second conductive material within the trench at the first location; and removing at least an uppermost part of the first conductive material that lines the trench at the first location to elevationally recess the first conductive material within the trench relative to an uppermost surface of the second conductive material at the first location.
