초록 | A leveler, one of the organic additives for Cu electrodeposition, is a key element for defect-free filling. The leveler assists bottom-up filling of Cu in via by its distinct characteristics so called convection-dependent adsorption. Although several levelers have been reported, their structure and property relationship has not been studied much. In this study, we synthesized four levelers having different structures including a TEG-based leveler that we had previously synthesized before. The electrochemical properties of the levelers were analyzed and turned out to be convection-dependent, however, the magnitude of suppression was clearly different. The gap-filling results of TSV-like trenches were also contained. |
