摘要:
A conductive polymer between two metallic layers acts a glue layer, a barrier layer or an activation seed layer. The conductive polymer layer is employed to encapsulate a copper interconnection structure to prevent copper diffusion into any overlying layers and improve adhesive characteristics between the copper and any overlying layers.
