Abstract: A method for forming semiconductor packages is disclosed. The method involves providing a support substrate and forming at least one conductive layer thereon. The method also includes coupling the at least one conductive layer to a support face of a film substrate for securing the at least one conductive layer to the support face and removing the support substrate from the at least one conductive layer. The at least one interconnector is adhered to the film substrate for forming an interposer. The method further involves bonding a integrated circuit chip to the at least one conductive layer of the interposer and disposing a compound over the support face to thereby encapsulate the integrated circuit chip and the least one conductive layer for forming an encapsulated package therefrom. Portions of the at least one conductive layer is then exposed by removing the film substrate from the encapsulated package.

A plurality of connectors for electrical transmission is disposed on the substrate and a plurality of pillars for facilitating electrical communication between the plurality of connectors and the integrated circuit chip is disposed between at least one of the plurality of connectors and the integrated circuit chip.

Abstract: High performance integrated circuits generally have high heat generating capabilities. During powering up of these integrated circuits under typical operating conditions, heat generation is unavoidably accelerated. When the accumulated heat is not adequately dissipated, the high temperature of the integrated circuits will lead to overheating which in turn, causes irreversible damage to the integrated circuits. Conventional thermal management methods using bumps of a ball grid array (BGA) as heat paths to a heat sink has low thermal transmissibility due to the substantially spherical shape thereof. Metallic columns formed by vias in substrates have dimensional restrictions that also limit thermal transmissibility thereof. Coupling of semiconductor device directly to a heat sink formed in a substrate will also require undesirable structural modifications to the substrate, for example a concavity formed therein, for accommodating the integrated circuit therewithin.
