Abstract(in English) | We found the bottom-up electroless plating of Cu by addition of SPS recently. In this study, effect of various additives such as alkanethiol and thiorea were investigated besides SPS. All these additives act as strong inhibitor for copper electroless plating. There was a clear bottom-up-fill effect for alkanethiol that had a hydrophilic unit. On the other hand, there was an anti-bottom-up effect for thiorea. These results suggested that there is a relationship between a molecular weight of inhibitor and the bottom-up-fill tendency. The bottom-up-fill occurs only when molecular weight is large enough, and it cannot occurs when molecular weight is much smaller than Cu-EDTA complex. |
