Patent ID: 6972444

Claim:
A semiconductor wafer comprising: a plurality of semiconductor circuits formed on the semiconductor wafer, each semiconductor circuit having a pair of first sides that are parallel to each other, and a pair of second sides that are parallel to each other and perpendicular to the pair of first sides; a plurality of first saw streets that run parallel to the first sides between a number of the semiconductor circuits, each first saw street extending in a straight line from an edge of the wafer to another edge of the wafer; a plurality of second saw streets that run parallel to the second sides between a number of the semiconductor circuits, each second saw street extending in a straight line from an edge of the wafer to another edge of the wafer; a first metal trace formed between a first saw street and a first semiconductor circuit, the first metal trace being electrically isolated from each semiconductor circuit and not crossing the first saw street; and a second metal trace formed between the first saw street and a second semiconductor circuit, the second metal trace being electrically isolated from each semiconductor circuit and not crossing the first saw street, the first saw street lying between the first semiconductor circuit and the second semiconductor circuit.
