Abstract
A local interconnect system for VLSI integrated circuits. After titanium is deposited for self-aligned silicidation of exposed moat and gate regions in a nitrogen atmosphere, a hardmask is deposited and patterned over the titanium. When a conductive titanium nitride layer is formed overall, it will already be patterned according to this hardmask.
