Abstract:
A system and method for packaging a semiconductor device that includes a wall to reduce electromagnetic coupling is presented. A semiconductor device has a substrate on which a first circuit and a second circuit are formed proximate to each other. An isolation wall of electrically conductive material is located between the first circuit and the second circuit, the isolation wall being configured to reduce inductive coupling between the first and second circuits during an operation of the semiconductor device. Several types of isolation walls are presented.
Abstract:
An embodiment of a radio-frequency (RF) device includes at least one transistor, a package, and a surface-mountable capacitor. The package contains the at least one transistor and includes at least one termination. The surface-mountable capacitor is coupled in a shunt configuration between the at least one transistor and a power supply terminal of the device to decouple the at least one transistor from a power supply.

Abstract:
A packaged semiconductor device may include a leadframe and a die carrier mounted to the leadframe. The die carrier is formed from an electrically and thermally conductive material. A die is mounted to a surface of the die carrier with die attach material having a melting point in excess of 240° C. A first electrical interconnect couples the die and the leadframe. A housing covers portions of the leadframe, die carrier, die and first electrical interconnect.

Abstract:
An embodiment of an electronic device includes a circuit component (e.g., a transistor or other component) coupled to the top surface of a substrate. Encapsulation is formed over the substrate and the component. An opening in the encapsulation extends from the encapsulation top surface to a conductive feature on the top surface of the component. A conductive termination structure within the encapsulation opening extends from the conductive feature to the encapsulation top surface. The device also may include a second circuit physically coupled to the encapsulation top surface and electrically coupled to the component through the conductive termination structure. In an alternate embodiment, the conductive termination structure may be located in a trench in the encapsulation that extends between two circuits that are embedded within the encapsulation, where the conductive termination structure is configured to reduce electromagnetic coupling between the two circuits during device operation.
