Abstract:
A thinfilm device for providing a fuse/antifuse function, comprising:a semiconductor substrate; a resistive fuse element formed on said substrate; a first electrode and a second electrode formed on said substrate and electrically coupled to said resistive fuse element, said resistive fuse element creating a first resistance between said electrodes in an initial state; an insulation layer provided over said first and second electrodes and said resistive fuse element; and a conductive material formed on said insulation layer and aligned with said resistive fuse element; wherein said device is fabricated without an ink well formed over said conductive material; and further wherein a first conductive path is provided in said substrate to said first electrode and a second conductive path is provided in said substrate to said second electrode, said first and second conductive paths being adapted for propagation of signals for both programming and reading the resistive fuse element via said first and second electrodes.
