Patent ID: 7842607

Claim:
A method of making a semiconductor device, comprising: providing a semiconductor die; forming first and second conductive vias around a perimeter of the semiconductor die; forming first and second conductive layers on a front side of the semiconductor die, the first conductive layer being electrically connected between the first conductive via and a contact pad of the semiconductor die, the second conductive layer being thermally connected to the second conductive via; forming third and fourth conductive layers on a backside of the semiconductor die opposite the front side of the semiconductor die, the third conductive layer being electrically connected to the first conductive via, the fourth conductive layer being thermally connected to the second conductive via; forming an insulating layer over the semiconductor die; removing a portion of the insulating layer to expose the first and second conductive layers and a thermal dissipation region of semiconductor die; forming a thermal via through the insulating layer to the second conductive layer; and forming a thermally conductive layer over the insulating material and thermal dissipation region and thermal via.
