Abstract
The embodiments described herein provide an antifuse that includes a substrate material and an isolation trench formed in the substrate material, where the isolation trench has a first side and a second side opposite the first side. An electrode is positioned above the substrate material and proximate to the first side of the isolation trench. An insulating layer is disposed between the electrode and the substrate material. So configured, a voltage or current applied between the electrode and the substrate material causes a rupture in the insulating layer and creates a current path through the insulating layer and under the isolation trench to the substrate material proximate the second side of the isolation trench.
