Abstract: A typical integrated-circuit fabrication requires interconnecting millions of microscopic transistors and resistors with aluminum wires. Making the aluminum wires flush, or coplanar, with underlying insulation requires digging trenches in the insulation, and then filling the trenches with aluminum to form the aluminum wires. Trench digging is time consuming and costly. Moreover, aluminum has higher electrical resistance than other metals, such as silver. Accordingly, the invention provides a new “self-trenching” or “self-planarizing” method of making coplanar silver wires. Specifically, one embodiment forms a first layer that includes silicon and germanium; oxidizes a region of the first layer to define an oxidized region and a non-oxidized region; and reacts silver with the non-oxidized region. The reaction substitutes, or replaces, the non-oxidized region with silver to form silver wires coplanar with the first layer.
