Application

Benzocyclobutene was used as the adhesive bonding material in adhesive wafer-level bonding technique[1]. Photosensitive benzocyclobutene has been widely used as dielectric material in multilayer packaging applications[2]. It was used in fabrication of high density multilayer interconnect structures using gold metallization and polymer interlayer dielectric[3].
