| 摘要 |
A method of repairing a semiconductor device includes forming a first conductive interconnection and a second conductive interconnection spaced from the first conductive interconnection on a semiconductor substrate, forming a magnetic fuse on the first conductive interconnection and forming a first contact plug on the second conductive interconnection, forming a metal interconnection on the magnetic fuse and the first contact plug, and applying a bias to the first conductive interconnection or to the second conductive interconnection corresponding to a normal cell or a redundancy cell and the metal interconnection. The method can readily prevent the problems caused in a laser cutting method without using a method of physically cutting a fuse by radiation of a laser when a semiconductor device fuse is repaired. |
