    Abstract: A method of making a photolithography mask for use in creating an electrical fuse on a semiconductor structure comprises initially determining a pattern for a desired electrical fuse, with the pattern including a fuse portion of substantially constant width except for a localized narrowed region of the fuse portion at which the electrical fuse is designed to blow. The method then includes providing a photolithography mask substrate and creating on the photolithography mask substrate a fuse mask element adapted to absorb transmission of an energy beam. The fuse mask element has a first mask portion of substantially constant width corresponding to the desired electrical fuse pattern portion of substantially constant width, and a second mask portion corresponding to the localized narrowed region of the fuse portion. The second mask portion comprises either an additional mask element spaced from the first mask portion, a narrowed width portion, or a gap in the first mask portion. The second mask portion is of a configuration sufficient to create a latent image of the electrical fuse pattern, including the localized narrowed region of the fuse portion at which the electrical fuse is designed to blow, upon passing the energy beam through the photolithography mask and onto a resist layer. Preferably, the fuse portion of substantially constant width on the determined fuse pattern has a design width less than about 0.25 mu m, and wherein the localized narrowed region of the fuse portion has a design width less than the design width of the fuse portion.

    Abstract: A fuse for semiconductor devices, in accordance with the present invention, includes a cathode (104) including a first dopant type, and an anode (102) including a second dopant type where the second dopant type is opposite the first dopant type. A fuse link (106) connects the cathode and the anode and includes the second dopant type. The fuse link and the cathode form a junction (111) therebetween, and the junction is configured to be reverse biased relative to a cathode potential and an anode potential. A conductive layer (103) is formed across the junction such that current flowing at the junction is diverted into the conductive layer to enhance material migration to program the fuse.

    Abstract: PROBLEM TO BE SOLVED: To improve the control of thickness of an insulator layer on a fuse structure, by a method wherein a dielectric structure is positioned on a conduction level, and electric connection is performed at a selected position of the conduction level through the dielectric structure. SOLUTION: On a semiconductor substrate 10 an electric conduction level 1 is formed by using conductive material selected out of aluminum, copper, aluminum copper alloy, and doped polysilicon having metal type conductivity. A dielectric etching stop material layer 2 is stuck on the upper surface of the electric conduction level 1. Electric connection is performed to a selected position of the electric conduction level 1 through the dielectric etching stop material layer 2, and a conductive fuse 21 is constituted. As a result control of the thickness of an insulator layer on the fuse structure containing a self-aligned isolation cap can be improved.

    Abstract: PROBLEM TO BE SOLVED: To array a larger number of fuses densely by electrically connecting at least two fuses that contain a fusing part arrayed in a first level of a multi- layer semiconductor device, respectively. SOLUTION: Each fuse 13 contains a part 15 that is actually fused. The part 15 to be fused is arrayed in a first metal level M1. Like the other part of the fuse 13, the part 15 that is actually fused is made typically of a electrically conductive material, especially aluminum. A termination of each part 15 to be fused is connected to a connector bias 17 that connects that fuse 13 with a connector 19. A gate contact 23 is vertical to a direction of the fuse 13. The gate contact 23 can be connected to a ground that is common to all of existing fuse circuits. Therefore, fuse density is doubled without narrowing the fuse pitch.
