Abstract: A wafer chip and a method of designing the chip is disclosed. A first fuse is formed having a first critical dimension and a second fuse having a second critical dimension are formed in a layer of the chip. A voltage may be applied to burn out at least one of the first fuse and the second fuse. The first critical dimension of the first fuse may result from applying a first mask to the layer and applying light having a first property to the mask. The second critical dimension of the second fuse may result from applying a second mask to the layer and applying light having a second property to the mask.
