Patent ID: 6919013

Claim:
An apparatus for use in manufacturing micro-sized structures in submicron micro-recesses on a microelectronic workpiece having a first layer over the micro-recesses and a copper seed layer over the first layer, the seed layer being a non-continuous layer having voids, wherein the apparatus comprises: a first reactor including a workpiece support and a reaction chamber adapted to hold a first electrochemical processing solution containing copper, the first reactor disposed to accept the microelectronic workpiece with the seed layer, and the first reactor being operated to electrochemically provide a conformal seed layer that covers at least a substantial portion of the first layer; and a second reactor including a workpiece support and a reactor chamber adapted to hold a second electrochemical processing fluid containing copper, the second reactor disposed to accept the microelectronic workpiece with the conformal seed layer, the second reactor being operated to electroplate additional copper onto the conformal seed layer to fill the micro-recesses on the workpiece, wherein the first reactor is operated to repair the seed layer using an electroplating process.
