Abstract:
1. A semiconductor device, comprising: a substrate having conductive interconnect formed on an active side thereof; and through die vias (TDVs) formed in the substrate between a backside and the active side thereof, the TDVs including signal TDVs, redundant TDVs, and power supply TDVs, the signal TDVs being spaced apart from the redundant TDVs to form a pattern of TDV pairs, the power supply TDVs being interspersed among the TDV pairs, wherein the conductive interconnect includes first signal conductors electrically coupling each of the signal TDVs to a respective one of the redundant TDVs defining a respective one of the TDV pairs; wherein, for each TDV pair of the TDV pairs, one TDV in the TDV pair is spaced closer to an unrelated TDV of the TDVs than the one TDV is spaced from the other TDV in the TDV pair.
