| Zusammenfassung: | A method for forming a fuse of a semiconductor device includes performing an ion-implanting process at sides of a fuse blowing region of a metal fuse, thereby increasing the concentration of impurity ions of a thermal transmission path region. In a subsequent laser blowing process, as a result of the increased resistance of metal fuse the electric and thermal conductivity is reduced, thereby increasing the thermal condensation efficiency of the fuse blowing region and improving the efficiency of the laser blowing process. |
