Abstract

The reliability of leadframe-based semiconductor package depends on the adhesion between metal and epoxy molding compound (EMC). In this study, the Ag surface was electrochemically treated in a solution containing silanes in order to improve the adhesion between Ag and epoxy substrate. After electrochemical treatment, the thin silane layer was deposited on the Ag surface, whereby the peel strength between Ag and epoxy substrate was clearly improved. The improvement of peel strength depended on the functional group of silane, implying the chemical linkage between Ag and epoxy.
