Abstract: In an example, an apparatus comprises a lead frame that includes a first row of leads, a first pad coupled to the first row of leads, and a second row of leads parallel to the first row of leads. The lead frame also includes a second pad coupled to the second row of leads. The first and second pads are separated by a gap, and each of the first and second pads has a substantially uniform thickness. The apparatus also includes a device coupled to the first and second pads. The first and second pads are exposed to an exterior of the apparatus.

Abstract: An example semiconductor package comprises a ceramic header having a first open space separated from a second open space by a ceramic barrier. A first heat sink is attached to a bottom of the ceramic header below the first open area. A first integrated circuit (IC) die is mounted on the first heat sink. A second heat sink is attached to a bottom of the ceramic header below the second open area. A second IC die is mounted on the second heat sink. A capacitive interface is disposed in the ceramic barrier between the first IC die and the second IC die. The capacitive has a plurality of capacitive elements alternating with a plurality of shielding elements. The capacitive elements are tunable over a range of capacitive values.

Abstract: An example semiconductor package comprises a ceramic header having a top surface and a cavity formed within the ceramic header. The cavity is open at the top surface. A semiconductor die is mounted within the cavity of the ceramic header. A lid structure is coupled to the top surface of the ceramic header. The lid structure and ceramic header form a portion of a package enclosing the semiconductor die. One or more silver tubes are in contact with a first surface of the semiconductor die and with a first surface of the lid structure. A seal ring is located between the top surface of the ceramic header and the lid structure. The seal ring couples the lid structure to the ceramic header. The one or more silver tubes are hollow and filled with a getter material.
