  • Publication number: 20230290747
    Abstract: Embodiments provide metal features which dissipate heat generated from a laser drilling process for exposing dummy pads through a dielectric layer. Because the dummy pads are coupled to the metal features, the metal features act as a heat dissipation feature to pull heat from the dummy pad. As a result, reduction in heat is achieved at the dummy pad during the laser drilling process.

  • Patent number: 11703541
    Abstract: A semiconductor inspecting method for ensuring a scrubbing length on a pad includes following steps. First off, a first position of a probe needle from above is defined. In addition, a wafer comprising at least a pad is placed on a wafer chuck of a semiconductor inspecting system. Thereafter, a relative vertical movement between the probe needle and the pad is made by adopting a driving system of the semiconductor inspecting system to generate a scrubbing length on the pad.
