  • Patent number: 9673157
    Abstract: In an embodiment of the present invention, a method of forming a semiconductor device includes providing a semiconductor substrate including a first chip region and a second chip region. A first contact pad is formed over the first chip region and a second contact pad is formed over the second chip region. The first and the second contact pads are at least as thick as the semiconductor substrate. The method further includes dicing through the semiconductor substrate between the first and the second contact pads. The dicing is performed from a side of the semiconductor substrate including the first contact pad and the second contact pad. A conductive liner is formed over the first and the second contact pads and sidewalls of the semiconductor substrate exposed by the dicing.

  • Publication number: 20160254200
    Abstract: A semiconductor component includes a semiconductor body having a bottom side, a top side spaced distant from the bottom side in a vertical direction, and a thickness in the vertical direction, and a crack sensor configured to detect a crack in the semiconductor body. The crack sensor extends into the semiconductor body. A distance between the crack sensor and the bottom side is less than the thickness of the semiconductor body. A crack in the semiconductor body is detected by specifying a first value of a characteristic variable of the crack sensor, determining a second value of the characteristic variable of the crack sensor at a different time than the first value is specified, and determining the semiconductor body has a crack if the second value differs from the first value by more than a pre-defined difference.
