  • Electronic fuse having heat spreading structure
    Patent number: 7888772
    Abstract: A semiconductor device includes a fuse transistor for fuse programming and a fuse block connected to the fuse transistor, wherein the fuse block comprises a fuse line and a heat spreading structure connected to the fuse line. The electrical fuse employs the heat spreading structure connected to the fuse line to prevent a rupture of the electrical fuse such that heat, which is generated in the fuse line during a blowing of the fuse line, is spread throughout the heat spreading structure. Thus, a sensing margin of the electrical fuse can be secured and a deterioration of devices adjacent to the electrical fuse by heat generated in the electrical fuse can be prevented.
    Type: Grant
