    摘要: An apparatus including a die including a dielectric material on a device side, an insulating layer surrounding a die area and embedding a thickness dimension of the die; and a carrier including a plurality of layers of conductive material disposed on the device side of the die, a first one of the layers of conductive materials being formed on the insulating layer and patterned into traces at least a portion of which are connected to respective contact points on the die. A method including disposing a die on a sacrificial substrate with a device side of the die opposite the sacrificial substrate; disposing a mold on the sacrificial substrate around; introducing an insulating material into a chase of the mold; removing the mold; forming a carrier on the insulating material adjacent a device side of a die; and separating the die and the carrier from the sacrificial substrate.
