Architecture of laser fuse box of semiconductor integrated circuit and method for fabricating the same

摘要

The invention relates to a fuse layout structure in a laser fuse box of a semiconductor integrated circuit and a method for fabricating the same. In one example of the invention, the fuse layout structure in a laser fuse box of the semiconductor integrated circuit includes a plurality of fuses with the central regions thereof extending parallel to each other within the fuse box, and the central regions of the fuses being covered with an insulative protection layer. Thus, the fuse layout structure of the present invention occupies a minimum area in the chip while minimizing influences of the heat generated by fusing neighboring fuses.
