Technical Examples

A typical integrated-circuit fabrication requires interconnecting millions of microscopic transistors and resistors with metal wires. Making the metal wires flush, or coplanar, with underlying insulation requires digging trenches in the insulation, and then filling the trenches with metal to form the wires. The invention provides a new "trench-less" or "self-planarizing" method of making coplanar metal 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 aluminum or an aluminum alloy with the non-oxidized region. The reaction substitutes, or replaces, the non-oxidized region with aluminum to form a metallic wire coplanar with the first layer. Another step removes germanium oxide from the oxidized region to form a porous insulation having a very low dielectric constant, thereby reducing capacitance.
