A method of manufacturing a packaged semiconductor device is provided. The method includes placing a plurality of semiconductor die on a carrier substrate. The plurality of semiconductor die and an exposed portion of the carrier substrate are encapsulated with an encapsulant. A cooling fixture includes a plurality of nozzles and is placed over the encapsulant. The encapsulant is cooled by way of air exiting the plurality of nozzles. A property of air exiting a first nozzle of the plurality of nozzles is different from that of a second nozzle of the plurality of nozzles.

Semiconductor device packaging warpage control

A method of manufacturing a semiconductor device packaging panel is provided. The method includes forming a panel having an active side and a backside. The panel includes a plurality of semiconductor die encapsulated with an encapsulant. An active surface of the semiconductor die is exposed on the active side of the panel. A warpage control carrier is attached onto the backside of the panel. The warpage control carrier includes an electroactive element configured for substantially flattening the panel while a control voltage is applied to the electroactive element.

A method of manufacturing a carrier for semiconductor device packaging is provided. The method includes forming a carrier having a plurality of plateau regions separated by a plurality of channels. The carrier is configured and arranged to support a plurality of semiconductor die during a packaging operation. The plurality of channels is filled with a material configured to control warpage of the carrier.

A semiconductor device having an integrated antenna is provided. The semiconductor device includes a base die having an integrated circuit formed at an active surface and a cap die bonded to the backside surface of the base die. A metal trace is formed over a top surface of the cap die. A cavity is formed under the metal trace. A conductive via is formed through the base die and the cap die interconnecting the metal trace and a conductive trace of the integrated circuit.

Semiconductor device having integrated antenna and method therefor

A method of manufacturing a semiconductor device packaging panel is provided. The method includes forming a panel by placing a plurality of semiconductor die on a major side of a carrier substrate and encapsulating with an encapsulant the plurality semiconductor die and the major side of the carrier substrate. A plurality of warpage control features are formed with the encapsulant while encapsulating. The method further includes placing the panel onto a warpage control fixture to substantially flatten the panel. The plurality of warpage control features interlock with mating features of the warpage control fixture.

Embodiments of inductive communication devices include first and second galvanically isolated IC die and a dielectric structure. Each IC die has a coil proximate to a first surface of the IC die. The IC die are arranged so that the first surfaces of the IC die face each other, and the first coil and the second coil are aligned across a gap between the first and second IC die. The dielectric structure is positioned within the gap directly between the first and second coils, and a plurality of conductive structures are positioned in or on the dielectric structure and electrically coupled with the second IC die. The conductive structures include portions configured to function as bond pads, and the bond pads may be coupled to package leads using wirebonds. During operation, signals are conveyed between the IC die through inductive coupling between the coils.
