摘要:
Patterned copper structures are fabricated by selectively capping the copper employing selective etching and/or selective electroplating in the presence of a liner material. Apparatus for addressing the problem of an increased resistive path as electrolyte during electroetching and/or electroplating flows from the wafer edge inwards is provided.
