Abstract
A high density, high performance circuit fabricated with a copper/epoxy structure. The circuit is well suited for an integrated circuit interconnect device. Fluorene-containing epoxy resins may be used to obtain certain material and processing advantages over copper/polyimide structures. The circuit structure resides on a substrate which may be ceramic, a semiconductor such as silicon, or, advantageously, a cured epoxy resin.
