A plurality of pulses each having relatively low energy are consecutively applied to a subject fuse to cause breakdown, wherein the total energy of pulses is set in light of a prescribed breakdown threshold, which is calculated in advance. The subject fuse has a pair of terminals and an interconnection portion that is narrowly constricted in the middle so as to realize fuse breakdown with ease. A pulse generator generates pulses, which are repeatedly applied to the subject fuse by way of a transistor; then, it stops generating pulses upon detection of fuse breakdown. Side wall spacers are formed on side walls of fuses, which are processed in a tapered shape so as to reduce thermal stress applied to coating insulating films. In addition, pulse energy is appropriately determined so as to cause electro-migration in the subject fuse, which is thus increased in resistance without causing instantaneous meltdown or evaporation.

A low-voltage anti-fuse element is provided with a first gate dielectric layer and a first gate sequentially disposed on a substrate. A first ion-doped region is formed in the substrate on one side of the first gate. The first gate includes a body portion and a sharp corner portion extending and gradually reducing from one side of the body portion both adjacent to the first gate dielectric layer. During the operation, the principle of higher density of charges at sharp corners is utilized. When the write voltage is applied between the first gate and the first ion-doped region, a portion of the first gate dielectric layer below the sharp corner portion is liable to break down. Therefore, the breakdown voltage is reduced to achieve the purpose of reducing current consumption, while decreasing the gate area, the element size and production costs.
