Abstract

A carrier having one or more conductive terminals is provided. A semiconductor die is mounted on the carrier. The semiconductor die is electrically connected to the one or more conductive terminals. The semiconductor die is encapsulated with an electrically insulating mold compound. A verification rule that tests whether inputted information satisfies authentication criteria is created. A first identification feature is formed on a metal structure that is encapsulated by the mold compound. The first identification feature comprises one or more symbols from a first data representation scheme that are covered by the mold compound. The one or more symbols of the first identification feature are selected to convey information that satisfies the authentication criteria of the verification rule.
