Abstract: A method for fabricating a semiconductor structure is disclosed. First, an interposer is disposed on a carrier. The carrier has a base body and a bonding layer bonded to the base body. The interposer has opposite first and second sides and the first side has a plurality of conductive elements. The interposer is disposed on the carrier with the first side bonded to the bonding layer and the conductive elements embedded in the bonding layer. Then, at least a semiconductor element is disposed on the second side of the interposer. As such, the semiconductor element and the interposer form a semiconductor structure. Since the conductive elements are embedded in the bonding layer instead of the base body, the present invention eliminates the need to form concave portions in the base body for receiving the conductive elements. Therefore, the method of the present invention is applicable to interposers of different specifications.

Abstract: A semiconductor package is provided. The semiconductor package includes a substrate; a semiconductor element having opposite active and inactive surfaces and disposed on the substrate via the active surface thereof, wherein the inactive surface of the semiconductor element is roughened; a thermally conductive layer bonded to the inactive surface of the semiconductor element; and a heat sink disposed on the thermally conductive layer. The roughened inactive surface facilitates the bonding between the semiconductor element and the thermally conductive layer so as to eliminate the need to perform a gold coating process and the use of a flux and consequently reduce the formation of voids in the thermally conductive layer.
