Semiconductor chip and semiconductor wafer
A semiconductor wafer includes at least one chip formed on a substrate, and a scribe line region surrounding the chip. The chip includes a device formation region, and a chip boundary region surrounding the device formation region and formed between the device formation region and the scribe line region. The chip boundary region includes a guard ring structure which physically separates the device formation region from the scribe line region. The guard ring structure includes a signal transfer element which transfers an electric signal between the device formation region and the scribe line region.
