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.

Semiconductor chip having a crack stop structure

A semiconductor device includes a semiconductor substrate having a first main surface and a metal structure above the first main surface. The metal structure has a periphery region that includes a transition section along which the metal structure transitions from a first thickness to a second thickness less than the first thickness. A polymer-based insulating material contacts and covers at least the periphery region of the metal structure. A thickness of the polymer-based insulating material begins to increase on a first main surface of the metal structure that faces away from the semiconductor substrate and continues to increase in a direction towards the transition section. An average slope of a surface of the polymer-based insulating material which faces away from the semiconductor substrate, as measured with respect to the first main surface of the metal structure, is less than 60 degrees along the periphery region of the metal structure.
