Abstract: An electronic device includes an integrated circuit chip mounted to a heat slug. The heat slug has a peripheral region having first thickness along a first direction, the peripheral region surrounding a recess region (having a second, smaller, thickness along the first direction) that defines a chip mounting surface along a second direction perpendicular to the first direction. The recess region defines side borders and a nook extends into the heat slug along the side borders. An insulating body embeds the integrated circuit one chip and heat slug. Material of the insulating body fills the nook.

Abstract: Embodiments are directed to a package that includes an electric device having a recess. In one embodiment, the electric device is a sensor and the recess reduces signal drift of the sensor caused by thermal expansion of the package. In another embodiment, the recess is substantially filled with adhesive material, thus increasing adhesion between the electric device and a substrate of the package while at the same time allowing for lower adhesive fillets.

Abstract: A surface mount package of a semiconductor device, has: an encapsulation, housing at least one die including semiconductor material; and electrical contact leads, protruding from the encapsulation to be electrically coupled to contact pads of a circuit board; the encapsulation has a main face designed to face a top surface of the circuit board, which is provided with coupling features designed for mechanical coupling to the circuit board to increase a resonant frequency of the mounted package. The coupling features envisage at least a first coupling recess defined within the encapsulation starting from the main face, designed to be engaged by a corresponding coupling element fixed to the circuit board, thereby restricting movements of the mounted package.

Abstract: An integrated circuit (IC) device includes an IC and encapsulating material surrounding the IC. Leads are coupled to the IC and extend outwardly from sides of the encapsulating material, with each lead having three contiguous exposed segments with upper and lower bends defining a Z-shape.
