Abstract:
1. A semiconductor device with a plurality of mark through substrate vias, comprising: a semiconductor substrate having a front surface and a backside surface; a plurality of original through substrate vias disposed in the semiconductor substrate, wherein the plurality of original through substrate vias comprise a plurality of first original through substrate vias and a plurality of second original through substrate vias, the plurality of first original through substrate vias are arranged in a first array, the plurality of second original through substrate vias are arranged in a second array, the pitch between two adjacent first original through substrate vias is defined as a first pitch, the pitch between two adjacent second original through substrate vias is defined as a second pitch; and a plurality of mark through substrate vias disposed in the semiconductor substrate and exposed from the backside surface, wherein the plurality of mark through substrate vias comprise a plurality of first mark through substrate vias and a plurality of second mark through substrate vias, the plurality of first mark through substrate vias are arranged in a first set, the plurality of second mark through substrate vias are arranged in a second set, the first set is disposed near the first array, the second set is disposed near the second array, the pitch between two adjacent first mark through substrate vias is defined as a third pitch, the pitch between the first original via nearest the first mark via and the first mark via is defined as a fourth pitch, the pitch between two adjacent second mark through substrate vias is defined as a fifth pitch, the pitch between the second original via nearest the second mark via and the second mark via is defined as a sixth pitch, wherein the third pitch is not equal to the fourth pitch, the third pitch and the fourth pitch are both indivisible by the first pitch, the fifth pitch is not equal to the sixth pitch, and the fifth pitch and the sixth pitch are both indivisible by the second pitch.
