  • Patent number: 8653624
    Abstract: Metal fuses in semiconductor devices may be formed on the basis of additional mechanisms for obtaining superior electromigration in the fuse bodies. To this end, the compressive stress caused by the current-induced metal diffusion may be restricted or reduced in the fuse body, for instance, by providing a stress buffer region and/or by providing a dedicated metal agglomeration region. The concept may be applied to the metallization system and may also be used in the device level, when fabricating the metal fuse in combination with high-k metal gate electrode structures.

  • Patent number: 8314625
    Abstract: In a test structure for determining dielectric breakdown events of a metallization system of semiconductor devices, a built-in compliance functionality may allow reliable switching off of the test voltage prior to causing high leakage currents, which may conventionally result in significant damage. Consequently, further failure analysis may be possible after the occurrence of a dielectric breakdown event.

  • Patent number: 8268679
    Abstract: In sophisticated integrated circuits, an electronic fuse may be formed such that an increased sensitivity to electromigration may be accomplished by including at least one region of increased current density. This may be accomplished by forming a corresponding fuse region as a non-linear configuration, wherein at corresponding connection portions of linear segments, the desired enhanced current crowding may occur during the application of the programming voltage. Hence, increased reliability and more space-efficient layout of the electronic fuses may be accomplished.

  • Publication number: 20120153479
    Abstract: In metallization systems of complex semiconductor devices, an intermediate interface layer may be incorporated into the interconnect structures in order to provide superior electromigration performance. To this end, the deposition of the actual fill material may be interrupted at an appropriate stage and the interface layer may be formed, for instance, by deposition, surface treatment and the like, followed by the further deposition of the actual fill metal. In this manner, the grain size issue, in particular at lower portions of the scaled inter-connect features, may be addressed.

  • Patent number: 8174010
    Abstract: A unified test structure which is applicable for all levels of a semiconductor device including a current path chain having a first half chain and a second half chain, wherein each half chain comprises lower metallization segments, upper metallization segments, an insulating layer between the lower metallization segments and the upper metallization segments, and connection segments. Each of the connection segments is electrically connected to a contact region of one of the lower metallization segments and to a contact region of one of the upper metallization segments to thereby electrically connect the respective lower metallization segment and the respective upper metallization segment, and the first half chain and the second half chain are of different configuration.

  • Patent number: 8153524
    Abstract: During the formation of complex metallization systems, a conductive cap layer may be formed on a copper-containing metal region in order to enhance the electromigration behavior without negatively affecting the overall conductivity. At the same time, a thermo chemical treatment may be performed to provide superior surface conditions of the sensitive dielectric material and also to suppress carbon depletion, which may conventionally result in a significant variability of material characteristics of sensitive ULK materials.
