A package for integrated circuits includes a base substrate having a mounting face. A first electronic chip has a top face electrically connected to the mounting face and a bottom face mounted to the mounting face by an adhesive layer. A second electronic chip has a bottom face covered with a thermal interface layer and a top face electrically connected to the mounting face. A heat sink includes a first part embedded in the adhesive layer, a second part having a bottom face in contact with the layer of thermal interface material and a top face, and a connection part between the first part and the second part. A coating encapsulates the first and second electronic chips and the heat sink. The top face of the second part of the heat sink exposed from the encapsulating coating.
