Abstract:
1. A semiconductor package, which comprises: a substrate having a front surface and a back surface, and whose front surface is defined as a die mounting area and a heat spreader attach area, and wherein the heat spreader attach area is formed with a plurality of recessed portions; at least one semiconductor chip mounted on the die mounting area of the substrate; an adhesive layer, which is coated over the heat spreader attach area of the substrate and substantially fills in the recessed portions in the heat spreader attach area of the substrate; and a heat spreader having a support portion and an elevated overhead portion, wherein the support portion is adhered by means of the adhesive layer to the heat spreader attach area of the substrate, with the elevated overhead portion coming in contact with the semiconductor chip for the purpose of heat dissipation from the semiconductor chip.
