Abstract
An antifuse element includes a conductive region formed in a semiconductor substrate extending in a first direction, a dielectric layer formed on a portion of the conductive region, a first conductive plug formed on the dielectric layer, a second conductive plug formed on another portion of the conductive region, a first conductive member formed over the first conductive plug, and a second conductive member formed over the second conductive plug. The dielectric layer has a first dielectric portion extending in a second direction, and a second dielectric portion extending in the first direction, in which the dielectric layer implements an electrical isolation between the conductive region and the first conductive plug. The first conductive plug has a first region of a first width and a second region of a second width, and the first width is greater than the second width.
