Electronic device with fuse structure and method for repairing the same

The invention relates to an electronic device with a fuse structure and a method for repairing the same. The electronic device includes a substrate, at least a conducting layer formed in or on the substrate and having a fuse area, and at least a lens disposed overlying the fuse area of the conducting layer, wherein the lens is substantially aligned with the fuse area and there is no optical device disposed between the lens and the fuse area. By disposing a lens between a fuse area of an electronic device and a light beam, repair or modification of a circuit of the electronic device may be efficiently performed. Additionally, the chip size and fuse layout pitch between nearby fuse areas of an electronic device thereof may be reduced. In addition, the cost of special machinery for producing the laser beam may also be reduced.
