Abstract
Described are methods for forming multi-component conductive structures for semiconductor devices. The multi-component conductive structures can include a common metal, present in different percentages between the two components of the conductive structures. As described example, multiple components can include multiple ruthenium materials having different percentages of ruthenium. In some applications, at least a portion of one of the ruthenium material components will be sacrificial, and removed in subsequent processing.
