An improved die seal ring is described which includes at least one break. In the region of the break in the die seal ring, the doping is modified so that the impedance of the electrical path across the break through the substrate is increased. Offsets in the break may also be used and the offset may be within a break in a track and/or between breaks in different tracks, where the die seal ring includes more than one track. |
