Abstract

At least one method, apparatus and system disclosed herein for forming a finFET device. A gate structure comprising a gate spacer on a semiconductor wafer is formed. A self-aligned contact (SAC) cap is formed over the gate structure. A TS structure is formed. At least one M0 metal structure void is formed. At least one CB structure void adjacent the M0 metal structure void is formed. An etch process is performed the M0 and CB structures voids to the gate structure. At least one CA structure void adjacent the CB structure void is formed. The M0, CB, and CA structure voids are metallized.
