Abstract:
A semiconductor chip includes a substrate having a frontside and a backside coupled to a ground. The chip includes a circuit in the substrate at the frontside. A through silicon via (TSV) having a front-end, a back-end, and a lateral surface is included. The back-end and lateral surface of the TSV are in the substrate, and the front-end of the TSV is substantially parallel to the frontside of the substrate. The chip also includes an antifuse material deposited between the back-end and lateral surface of the TSV and the substrate. The antifuse material insulates the TSV from the substrate. The chip includes a ground layer insulated from the substrate and coupled with the TSV and the circuit. The ground layer conducts a program voltage to the TSV to cause a portion of the antifuse material to migrate away from the TSV, thereby connecting the circuit to the ground.
