ABSTRACT:
The melting of a fuse of a CMOS type integrated circuit is caused by using the existence of a stray thyristor created in the neighborhood of the boundaries of pads made in a substrate. This stray thyristor is triggered by artificially making the potential drop in an intermediate region of the pad. The thyristor always comes on suddenly, the current that flows through the thyristor is very high and the phenomenon stops spontaneously when the fuse is melted.
