Abstract:
1. An apparatus, comprising: a semiconductor chip supported on a chip island; a filler layer encapsulating the semiconductor chip; a heat sink; through contacts extending, through the filler layer to an upper surface of the filler layer, the through contacts separated from the heat sink by a first trench cut into the upper surface of the filler layer, the through contacts being separated by a second trench from a vertical wall of the filler layer adjacent to the upper surface of the filler layer, the through contacts lying between the first trench and the second trench, the through contacts having exposed areas positioned along an outer edge of the first and second trenches, the exposed areas separated from each other by regions of the filler layer, wherein the heat sink terminates flush with an inner edge of the first trench and the first trench contains an electrically insulating material; and contact bumps, partially embedded within the filler layer and connected to an upper surface of the semiconductor chip by bonding wires, wherein the chip island, the through contacts, and the contact bumps terminate flush with a lower surface of the filler layer.
