Abstract
A zinc-based temporary electrical connection (e.g., a microfuse) useful in electroplating isolated conductor (i.e., copper) structures and copper/polyimide high-density interconnect structures are disclosed. The microfuse includes a zinc conductor layer, and in some embodiments, additional silicon adhesion and silicon protection layers. The microfuse is conductive, and therefore useful in an electroplating process, until it is treated (e.g., heated to about 400.degree. C. for one hour), to convert it into an insulator due to zinc oxidation, and remains in this state.
