    摘要: An integrated circuit system comprising a first integrated and at least one of a second integrated circuit, interposer or printed circuit board. The first integrated circuit further comprising a wiring stack, bond pads electrically connected to the wiring stack, and bump balls formed on the bond pads. First portions of the wiring stack and the bond pads form a functional circuit, and second portions of the wiring stack and the bond pads form a test circuit. A portion of the bump balls comprising dummy bump balls. The dummy bump balls electrically connected to the second portions of the wiring stack and the bond pads. The at least one of the second integrated circuit, interposer orprinted circuit board forming a portion of the test circuit.

    摘要: A customized seal ring for a semiconductor device is formed of multiple seal ring cells that are selected and arranged to produce a seal ring design. The cells include first cells that are coupled to ground and second cells that are not coupled to ground. The second cells that are not coupled to ground, include a higher density of metal features in an inner portion thereof, than the first seal ring cells. Dummy metal vias and other metal features that may be present in the inner portion of the second seal ring cells are absent from the inner portion of the first seal ring cells that are coupled to ground. The seal ring design may include various arrangements, including alternating and repeating sequences of the different seal ring cells.

    摘要: An integrated circuit includes a seal ring structure disposed around a circuit that is disposed over a substrate. A first pad is electrically coupled with the seal ring structure. A leakage current test structure is disposed adjacent to the seal ring structure. A second pad electrically coupled with the leakage current test structure, wherein the leakage current test structure is configured to provide a leakage current test between the seal ring structure and the leakage current test structure.
