Abstract:
A semiconductor device with an anti-pad peeling structure is disclosed. The semiconductor device includes: a semiconductor substrate including a Through Substrate Via (TSV); a dielectric layer on the semiconductor substrate and including a plurality of recesses therein; and a pad above the semiconductor substrate to cover a portion of the dielectric layer and extend to the recesses; wherein the pad extends to the plurality of recesses, and a plurality of contact points are confined in the recesses between the pad and the conductive layer, and each of the contact points is at least partially excluded from a boundary of the TSV when being seen from a top-down perspective.
