A protective modular package assembly with one or more subassemblies, each having a base element, a sidewall element coupled to the base element, and a semiconductor device disposed within and coupled to the sidewall element and the base element; a protective modular package cover having fastening sections located at opposing ends of the cover, torque elements disposed on the opposing ends and configured to fasten the cover to a core, and subassembly receiving sections disposed between the fastening sections with each subassembly receiving section operable to receive a subassembly and having a cross member along the underside of the cover; and an adhesive layer configured to affix subassemblies to respective subassembly receiving sections. The torque elements are configured to transfer a downward clamping force generated at the fastening elements to a top surface of the subassemblies via the cross member of each of the one or more subassembly receiving sections.
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.

Abstract:
According to the present invention, schottky diode technology is used to limit the amount of stored charge which must be overcome by an RF transistor during the portion of an RF cycle when the RF transistor attempts to turn on. Limiting the amount of stored charge stabilizes the bias point of the RF transistor on its load line so that the mode of operation of the RF transistor may be maintained. Thus, a schottky diode is placed in a RF transistor circuit and acts as a current sink to bleed stored charge to ground. Placement of the schottky diode close to the RF transistor provides a number of benefits, including introduction of the schottky diode at a low impedance point of the RF transistor circuit, minimization of lead/lag phase angles introduced by intervening matching elements, and minimization of resonance effects. The maximum benefit may be realized by placing the schottky diode as close to the RF transistor as possible, with especially good results possible by placing the schottky diode inside the RF transistor package, such as on a MOSCAP or on the RF transistor die itself. Furthermore, placement of the schottky diode within the matching network of the RF transistor limits the maximum negative deviation of the input signal to -0.2 to -0.3 volts. Placement of the schottky diode within the RF transistor package causes the schottky diode to be forward biased during the negative half of the RF input cycle, thereby not allowing the RF transistor's base-emitter junction to be sufficiently reverse biased to store charge.
