Abstract:
A fuse structure, comprising:a substrate; a first conductive layer formed on part of the substrate; a dielectric layer formed on the substrate and the first conductive layer; a second conductive layer comprising a position of laser spot formed on part of the dielectric layer; a third conductive layer formed on the part of the dielectric layer placed above the first conductive layer and corresponding to the first conductive layer, wherein the third conductive layer is insulated from the first and second conductive layers, and the second conductive layer and the third conductive layer are arranged in a straight line; a passivation layer having a window formed on the second conductive layer and the third conductive layer; and at least one conductive plug penetrating the dielectric layer, to electrically connect the first conductive layer and the second conductive layer, wherein the window exposes the second conductive layer comprising the position of laser spot, part of the third conductive layer and part of the dielectric layer.
