A semiconductor device includes a semiconductor die having contact pads disposed over a surface of the semiconductor die, a die attach adhesive layer disposed under the semiconductor die, and an encapsulant material disposed around and over the semiconductor die. The semiconductor device further includes bumps disposed in the encapsulant material around a perimeter of the semiconductor die. The bumps are partially enclosed by the encapsulant material. The semiconductor device further comprises first vias disposed in the encapsulant. The first vias expose surfaces of the contact pads. The semiconductor device further includes a first redistribution layer (RDL) disposed over the encapsulant and in the first vias, and a second RDL disposed under the encapsulant material and the die attach adhesive layer. The first RDL electrically connects each contact pad of the semiconductor die to one of the bumps, and the second RDL is electrically connected to one of the bumps.

A semiconductor device is made by providing a metal substrate for supporting the semiconductor device. Solder bumps are connected to the substrate. In one embodiment, a conductive material is deposited over the substrate and is reflowed to form the solder bumps. A semiconductor die is mounted to the substrate using a die attach adhesive. The semiconductor die has a plurality of contact pads formed over a surface of the semiconductor die. An encapsulant material is deposited over the solder bumps and the semiconductor die. The encapsulant is etched to expose the contact pads of the semiconductor die. A first redistribution layer (RDL) is formed over the encapsulant to connect each contact pad of the semiconductor die to one of the solder bumps. The substrate is removed to expose the die attach adhesive and a bottom surface of the solder bumps.

A semiconductor device is made by forming solder bumps over a copper carrier. Solder capture indentations are formed in the copper carrier to receive the solder bumps. A semiconductor die is mounted to the copper carrier using a die attach adhesive. The semiconductor die has contact pads formed over its active surface. An encapsulant is deposited over the copper carrier, solder bumps, and semiconductor die. A portion of the encapsulant is removed to expose the solder bumps and contact pads. A conductive layer is formed over the encapsulant to connect the solder bumps and contact pads. The conductive layer operates as a redistribution layer to route electrical signals from the solder bumps to the contact pads. The copper carrier is removed. An insulating layer is formed over the conductive layer and encapsulant. A plurality of semiconductor devices can be stacked and electrically connected through the solder bumps.
