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.
