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: A leadframe includes a die pad and a set of electrically conductive leads. A semiconductor die, having a front surface and a back surface opposed to the front surface, is arranged on the die pad with the front surface facing away from the die pad. The semiconductor die is electrically coupled to the electrically conductive leads. A package molding material is molded over the semiconductor die arranged on the die pad. A stress absorbing material contained within a cavity delimited by a peripheral wall on the front surface of the semiconductor die is positioned intermediate at least one selected portion of the front surface of the semiconductor die and the package molding material.

Abstract: A support substrate has a face above which at least one electronic component is fixed. A peripheral area of the face includes an annular local metal layer. An encapsulating cover for the electronic component includes a peripheral wall having an end edge that is mounted above the peripheral area. The annular metal local layer includes, at the periphery thereof, a series of spaced-apart teeth with notches formed therebetween. The teeth extend as far as the peripheral edge of the support substrate.

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) module for an IC card includes a plurality of IC card contacts in side-by-side relation. A dielectric support layer is above the contact layer and has a plurality of openings and a first coefficient of thermal expansion (CTE). An IC die is above the dielectric support layer and includes a plurality of bond pads. A bond wire extends from a respective bond pad to a corresponding contact through an adjacent opening in the dielectric support layer. A respective body of fill material is within each opening and has a second CTE. A mold compound body is above the dielectric support layer, the bodies of fill material, and surrounding the IC die. The mold compound body has a third CTE. The first CTE is closer to the second CTE than to the third CTE.
