Abstract
An anti-fuse element that includes an insulation layer; a pair of electrode layers formed on upper and lower surfaces of the insulation layer; and an extraction electrode contacting a section of the electrode layers forming electrostatic capacitance with the insulation layer. The anti-fuse element is configured to create a structural change section that includes a short circuit section short-circuited such that the pair of electrode layers are fused mutually to engulf the insulation layer, and a dissipation section with the electrode layers and insulation layer dissipated by the engulfing of the insulation layer, when a voltage not less than the breakdown voltage of the insulation layer is applied. The maximum diameter of a section of the extraction electrode in contact with the electrode layer is larger than the maximum diameter of the structural change section.
