Abstract
A support substrate supports an electronic chip. An encapsulation coating on the support substrate coats the electronic chip. The encapsulation coating includes a trench surrounding the electronic chip. A heat sink is mounted to the encapsulation coating above the electronic chip. The heat sink is fixed to the encapsulation coating by an adhesive material and a thermal interface material layer is present between the electronic chip and the heat sink. The trench is positioned between the thermal interface material layer and the adhesive material.
