  • Patent number: 8338952
    Abstract: A method for fabricating an interconnect structure for interconnecting a semiconductor substrate to have three distinct patterned structures such that the interconnect structure provides both a low k and high structural integrity. The method includes depositing an interlayer dielectric onto the semiconductor substrate, forming a first pattern within the interlayer dielectric material by a first lithographic process that results in both via features and ternary features being formed in the interconnect structure. The method further includes forming a second pattern within the interlayer dielectric material by a second lithographic process to form line features within the interconnect structure. Hence the method forms the three separate distinct patterned structures using only two lithographic processes for each interconnect level.

  • Patent number: 8278758
    Abstract: Embodiments of an on-chip interconnect having a multilevel reservoir are provided. In general, the on-chip interconnect is an interconnect within an integrated circuit and includes an interconnect segment and a multilevel reservoir. The interconnect segment has an anode end and a cathode end. The multilevel reservoir is adjacent to the cathode end of the interconnect segment and operates as a reservoir of metal atoms. As such, any electromigration-induced void begins forming in the multilevel reservoir rather than the cathode end of the interconnect segment. As a result, a reliability of the on-chip interconnect is substantially improved as compared to that of traditional on-chip interconnects. In addition, by utilizing multiple levels of the integrated circuit, a volume of the multilevel reservoir is substantially increased as compared to a volume of a corresponding single-level reservoir.
