ABSTRACT:
This invention relates to an interconnection structure comprising one or more insulating films and one or more layers of conductor electrode patterns, wherein at least one of the insulating films consists of a fluorene skeleton-containing epoxy acrylate resin, and to a method of making a multilayer interconnection structure including the steps of roughening the surface of an insulating resin layer and forming a conductor thereon by electroless plating, wherein the average roughness (Ra), maximum roughness (Ry) and conductor thickness (T) of the roughened surface of the insulating resin layer satisfy the following relations:
