Patent ID: 7196416

Claim:
Electronic device comprising: a first chip having an active side and a back side, on which active side the first chip has first and second conductive interconnections; a second chip having an active side and a back side, on which active side the second chip has first conductive interconnections, the active sides of the first and second chips facing each other, the first conductive interconnections of the chips being mutually connected in electroconductive manner by first metal interconnections; a substrate having a first side and an opposite second side, which first side faces the active side of the first chip, which substrate comprises a heat sink, conductive interconnections and contact surfaces for external contacting, which heat sink is connected by conductive adhesive with the back of the second chip and which conductive interconnections are electroconductively connected by a second metal interconnection to the second conductive interconnections of the first chip, and which contact surfaces can be contacted on the second side of the substrate; and an encapsulation of passivating material which envelops the first and second chips and the metal interconnections at any rate substantially and to which the substrate is attached.
