Abstract
A semiconductor device is made by forming a heat spreader over a temporary carrier. A semiconductor die is mounted to the heat spreader. A first polymer layer is formed over the semiconductor die and heat spreader. A first conductive layer is formed over the first polymer layer. The first conductive layer is connected to the heat spreader and contact pads on the semiconductor die. A second polymer layer is formed over the first conductive layer. A second conductive layer is formed over the second polymer layer. The second conductive layer is electrically connected to the first conductive layer. Bumps are formed through a solder masking layer on the second conductive layer. The temporary carrier is removed. The heat spreader dissipates heat from the semiconductor die and provides shielding from inter-device interference. The heat spreader is grounded through the first and second conductive layers.
