  • Patent number: 9917040
    Abstract: A package is formed by a thermal base and a leadframe assembly. The thermal base includes a body of thermally conductive material having a top surface, wherein the top surface of the body includes a pedestal. An integrated circuit chip is mounted to the pedestal, the integrated circuit chip including bonding pads. The leadframe assembly includes leads and an encapsulant ring that partially embeds the leads. The leadframe assembly is mounted to the top surface of said body surrounding the pedestal. The pedestal is configured with a thickness that positions the bonding pad at a height substantially coplanar with the leads. Bonding wires extend from the bonding pads to the leads with a shortened length so as to provide for improved electrical characteristics of frequency response, impedance and inductance.

  • Patent number: 8980747
    Abstract: Pre-migration of metal ions is achieved in a controlled manner to form a migrated metalover which an inhibitor is applied to prevent further migration. In a semiconductor circuit, pre-migration of metal ions is achieved by exposing a joined metal system to water, oxygen and an electrical field in a controlled manner. Conductors, joined to electrically isolating materials, are exposed to electrical fields in such a manner as to form one or more anodes to corresponding cathodes, thus liberating metal ions. The metal ions are then allowed to migrate in a controlled manner from the anode toward the cathode to form a pre-migrated metal. Finally, an inhibitor is applied on top of the pre-migrated metal to prevent further migration.

  • Patent number: 8557703
    Abstract: According to an embodiment of the present disclosure, a method of pre-migrating metal ions is disclosed. A metal in a semiconductor configuration is exposed to water and oxygen to yield metal ions. The metal couples a conductor to another material. The metal and the conductor are exposed to an electrical field in such a manner that one or both of the metal and the conductor becomes an anode to a corresponding cathode. The metal ions are then allowed to migrate from the anode to the cathode to form a migrated metal. Finally, a migration inhibitor is applied on top of the migrated metal to prevent further migration.
