    摘要: A programmable package with a fuse embedded therein, and fabrication method are provided. The fuse has first and second terminal ends joined by a central portion defining a fusible link. The ends include a portion of the first and second conductive layers, the central portion including a portion of the first conductive layer. The first layer may be electroless copper and the second layer may be electrolytic copper. The fuse may have a dog-bone or a bow tie shape. The method includes providing a substrate with a dielectric layer, and forming the fuse by depositing first conductive layer, forming and patterning second conductive layer over a portion of the first layer, and patterning first layer to form interconnects between areas of the second layer.
