Edge removal for through-resist plating |
abstract |
An electroplating cup assembly comprises a cup bottom, a lip seal, and an electrical contact structure. The cup bottom at least partially defines an opening configured to allow exposure of a wafer positioned in the cup assembly to an electroplating solution. The lip seal is on the cup bottom and comprises a sealing structure extending upwardly along an inner edge of the lip seal to a peak that is configured to be in contact with a seed layer of a wafer and adjacent to a sacrificial layer of the wafer. The electrical contact structure is over a portion of the seal. The electrical contact structure configured to be coupled to the seed layer of the wafer. |
