Abstract

This paper presents studies of surface modifications of benzocyclobutene (BCB) using reactive ion etching (RIE), ion implantation, and combinations of those in conjunction with liftoff processing steps. It was found that O2/N2 RIE treatments of the BCB surface improve the adhesion of subsequently evaporated chromium and copper. Implant treatments with C+, O+, Si+, As+, and Sb+, were also investigated. The implant treated samples exhibited improved adhesion prior to subsequent heat treatments in the Cr/BCB structures and some improvement subsequent to heat treating in the Cu/BCB structures. Combinations of the surface modification treatments were seen to have the greatest benefit, even after heat treatments.
