Abstract: A chip package includes a chip, an insulating layer, a flowing insulating material layer and conductive layer. The chip has a conductive pad, a side surface, a first surface and a second surface opposite to the first surface, which the side surface is between the first surface and the second surface, and the conductive is below the first surface and protruded from the side surface. The insulating layer covers the second surface and the side surface, and the flowing insulating material layer is disposed below the insulating layer, and the flowing insulating material layer has a trench exposing the conductive pad protruded form the side surface. The conductive layer is disposed below the flowing insulating material layer and extended into the trench to contact the conductive pad.

Abstract: A chip package includes a chip, an insulating layer and a conductive layer. The chip includes a substrate, an epitaxy layer, a device region and a conductive pad. The epitaxy layer is disposed on the substrate, and the device region and the conductive pad are disposed on the epitaxy layer. The conductive pad is at a side of the device region and connected to the device region. The conductive pad protrudes out of a side surface of the epitaxy layer. The insulating layer is disposed below the substrate and extended to cover the side surface of the epitaxy layer. The conductive layer is disposed below the insulating layer and extended to contact the conductive pad. The conductive layer and the side surface of the epitaxy layer are separated by a first distance.
