Abstract
A layer of zirconium can be used as an adhesion layer between a ceramic or polyimide substrate and subsequently applied metallic layers. Following the zirconium layer, copper can be deposited followed by a reaction barrier layer and a wettable surface layer such as gold. This type of structure can be used for pin bracing, chip joining, and/or wire connections.
