Recently, I have examined the impact of additives for TSV filling using CVS method (cyclic voltammetry stripping). To be specific, I measure anode charge when working electrode rotating at 10 (A10) and 1000 (A1000) rpm and the result should be A10 smaller than A1000 with the appearance of additives. However, my results were completely different than expected. I think I might be wrong in some steps. If any researchers have faced this problem before and already fixed it, please recommend for me some feasible solution. Thanks in advance.
