    摘要: A non-ablative structure and method for forming a variable resistor includes providing a programmable resistive element including two or more different conductive materials, and changing a resistance of the programmable resistive element to a finite value by heating the programmable element by either providing a current flow through the programmable element, or directing a laser beam onto the programmable element. The conductive materials are interdiffused to form an alloy of the conductive materials. A resistance value of the variable resistor is determined, at least in part, by the degree to which the conductive materials are alloyed or interdiffused. The method and structure of the variable resistor prevents ablative damage to adjoining circuit structure, allowing tighter pitch, and has application to digital programmable elements, and to resistance trimming for impedance matching in RF integrated circuits.

    摘要: A method and structure for a fuse structure comprises an insulator layer, a plurality of fuse electrodes extending through the insulator layer to an underlying wiring layer, an electroplated fuse element connected to the electrodes, and an interface wall. The fuse element is positioned external to the insulator, with a gap juxtaposed between the insulator and the fuse element. The interface wall further comprises a first side wall, a second side wall, and an inner wall, wherein the inner wall is disposed within the gap. The fuse electrodes are diametrically opposed to one another, and the fuse element is perpendicularly disposed above the fuse electrodes. The fuse element is either electroplatted, electroless plated, or is an ultra thin fuse.
