LOW COST RELIABLE FAN-OUT FAN-IN CHIP SCALE PACKAGE
A microelectronic device, in a fan-out fan-in chip scale package, has a die and an encapsulation material at least partially surrounding the die. Fan-out connections from the die extend through the encapsulation material and terminate adjacent to the die. The fan-out connections include wire bonds, and are free of photolithographically-defined structures. Fan-in/out traces connect the fan-out connections to bump bond pads. The die and at least a portion of the bump bond pads partially overlap each other. The microelectronic device is formed by mounting the die on a carrier, and forming the fan-out connections, including the wire bonds, without using a photolithographic process. The die and the fan-out connections are covered with an encapsulation material, and the carrier is subsequently removed, exposing the fan-out connections. The fan-in/out traces are formed so as to connect to the exposed portions of the fan-out connections, and extend to the bump bond pads.

LOW COST RELIABLE FAN-OUT CHIP SCALE PACKAGES
A microelectronic device, in a fan-out chip scale package, has a die and an encapsulation material at least partially surrounding the die. The microelectronic device includes bump bond pads adjacent to the die that are exposed by the encapsulation material, the bump bond pads being free of photolithographically-defined structures. Wire bonds connect the die to the bump bond pads. The microelectronic device is formed by mounting the die on a carrier, and forming the bump bond pads adjacent to the die without using a photolithographic process. Wire bonds are formed between the die and the bump bond pads. The die, the wire bonds, and the bump bond pads are covered with an encapsulation material, and the carrier is subsequently removed, exposing the bump bond pads.
