Abstract
Device packages often include walls build on a heat sink that surrounds a device die that thermally interacts with the heat sink. Use of raised or depressed feature on said heat sink that contacts the walls improves the cohesiveness of the package. By appropriately positioning these features contaminant infusion into the package is improved without degrading cohesiveness.
