Abstract:
The present invention relates to an electrode assembly useful for analyzing metal electroplating solutions. Such electrode assembly comprises a measuring electrode, preferably a rotating disc electrode or a microelectrode, and at least one of an in situ cleaning mechanism, a nucleation and metal growth optimization mechanism, and a voltage limiting mechanism. The present invention also relates to usage of such electrode assembly for in situ cleaning of the measuring electrode, nucleation and metal growth optimization, or voltage limitation.

Abstract:
Chemical mechanical polishing (CMP) compositions and single CMP platen process for the removal of copper and barrier layer material from a microelectronic device substrate having same thereon. The process includes the in situ transformation of a Step I slurry formulation, which is used to selectively remove and planarize copper, into a Step II slurry formulation, which is used to selectively remove barrier layer material, on a single CMP platen pad.
