Abstract
A tunable antifuse element () includes a substrate material () having an active area () formed in a surface, a gate electrode () having at least a portion positioned above the active area (), and a dielectric layer () disposed between the gate electrode () and the active area (). The dielectric layer () includes a tunable stepped structure (). During operation, a voltage applied between the gate electrode () and the active area () creates a current path through the dielectric layer () and a rupture of the dielectric layer () in a rupture region (). The dielectric layer () is tunable by varying the stepped layer thicknesses and the geometry of the layer.
