Abstract:
Provided is a semiconductor chip. The semiconductor chip includes a semiconductor substrate including a main chip region and a scribe lane region surrounding the main chip region. An insulating layer is disposed over the semiconductor substrate. A guard ring is disposed in the insulating layer in the scribe lane region. The guard ring surrounds at least a portion of the main chip region. The guard ring has a brittleness greater than a brittleness of the insulating layer.
