Abstract:
The present disclosure provides a method for reducing large particle counts (LPCs) in copper chemical mechanical polishing slurry by way of using high purity removal rate enhancer (RRE) in the slurry. The conductivity of the RRE in deionized water solutions correlates very strongly with the number of LPCs in the RRE, and thus in a slurry using the RRE.

Claim (Index 1):
A copper chemical mechanical polishing composition, comprising:\n a removal rate enhancer; a corrosion inhibitor; an abrasive; wherein the removal rate enhancer has a conductivity C in deionized water, and wherein the removal rate enhancer obeys the following inequality:\n C\u2264a*W+b,  \n wherein W is the wt % of the removal rate enhancer, based on the total weight of the composition, wherein 0.0005<a<0.0025, and wherein 0.0005<b<0.0025, wherein the composition has a large particle count, wherein the large particle count is defined by the number of particles per milliliter of the composition having a size greater than 0.56 micrometers, and wherein the conductivity C and the large particle count have a positive correlation, such that the lower the conductivity, the lower the large particle count.
