Abstract: A stack of chips is formed by a first integrated-circuit chip and a second integrated-circuit chip. The chips have opposing faces which are separated from each other by an interposed spacer. The spacer is fastened by adhesion to only one of the opposing faces. The opposing faces are fastened to each other by a local adhesive which is separate from spacer.

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.
