Abstract:
A semiconductor chip having a crack stop structure is disclosed. The crack stop structure includes one or more recesses formed in the semiconductor chip. The one or more recesses extend adjacent to and along a periphery of the semiconductor chip. The one or more recesses are filled with a metal material. The metal material has an intrinsic tensile stress at room temperature that induces compressive stress in at least a region of the periphery of the semiconductor chip.
