    摘要: A semiconductor test pad interconnect structure with integrated die-separation protective barriers. The interconnect structure includes a plurality of stacked metal layers each having an electrically conductive test pad separated from other test pads by a dielectric material layer. In one embodiment, at least one metallic via bar is embedded into the interconnect structure and electrically interconnects each of the test pads in the metal layers together. The via bar extends substantially along an entire first side defined by each test pad in some embodiments. In other embodiments, a pair of opposing via bars may be provided that are arranged on opposite sides of a die singulation saw cut line defined in a scribe band on a semiconductor wafer.

    摘要: An integrated circuit parametric testline providing increased test pattern areas is disclosed. The testline comprises a dielectric layer over a substrate, a plurality of probe pads over the dielectric layer, and a first device under test (DUT) formed in the testline in a space underlying the probe pads. The testline may also include a second DUT, which is formed in a space underlying the probe pads overlying the first DUT in an overlaying configuration. The testline may further include a polygon shaped probe pad structure providing an increased test pattern area between adjacent probe pads.

    摘要: In one embodiment, the disclosure relates to a method and apparatus for inserting dummy patterns in sparsely populated portions of a metal layer. The dummy pattern counters the effects of variations of pattern density in a semiconductor layout which can cause uneven post-polish film thickness. An algorithm according to one embodiment of the disclosure determines the size and location of the dummy patterns based on the patterns in the metal layer by first surrounding the metal structure with small dummy pattern and then filling any remaining voids with large dummy patterns.
