Self-Aligned Contact (SAC) is a semiconductor process flow technique that adds a protective dielectric layer over the transistor gate in order to prevent contact-to-gate shorts. SAC is used to enable aggressive scaling of the contacted poly pitch while minimizing yield loss due to misalignment and partial overlaps of the contacts over the gate.
