Electroplating leveler
WebMLI’s TSV chemistries include fast filling, high purity accelerator, suppressor, and leveler organic additives. The chemistry is based on a high purity sulfuric acid, copper sulfate based electrolyte. The combination of organic additives and electrolyte allows for a highly economical chemistry that provides fast, bottom-up fill of TSV’s ... WebOct 15, 2024 · The levelers lifetime and its effect after a long-term time period use were evaluated by periodic continuous electroplating test. The filling rate and relative filling rate of the levelers at different cycle numbers during the periodic continuous electroplating test are shown in Fig. 11 a and b .
