Claim:
1. A structure comprising: a die substrate; a passivation layer on the die substrate, a distal surface of the passivation layer being away from the die substrate; a first interconnect structure on the passivation layer, the first interconnect structure comprising a first via portion through the passivation layer to a first conductive feature of the die substrate, the first interconnect structure further comprising a first pad and a first transition element on the distal surface of the passivation layer between the first via portion and the first pad; a second interconnect structure on the passivation layer, the second interconnect structure comprising a second via portion through the passivation layer to a second conductive feature of the die substrate, the second interconnect structure further comprising a second pad and a second transition element on the distal surface of the passivation layer between the second via portion and the second pad; and a barrier disposed between the first pad and the second pad, the barrier being in direct contact with the distal surface of the passivation layer, wherein the barrier directly contacts at least one of the first interconnect structure or the second interconnect structure, or a combination thereof, the barrier not fully encircling at least one of the first pad or the second pad.
