Abstract:
A module for an electronic device comprising:at least one semiconductor component and an electrical bus; wherein said semiconductor component is metallurgically attached to said electrical bus, said electrical bus is an electrically conductive heat sink for said semiconductor component, said heat sink comprising an enclosed housing with at least one throughway therein to allow passage of a heat transfer fluid through said heat sink, said electrically conductive heat sink that is said electrical bus has at least one surface formed from a material that is electrically and thermally conductive that is the mounting surface for said semiconductor component, said material having a coefficient of thermal expansion approximating that of a substrate of said semiconductor component, and said semiconductor component is attached directly to said mounting surface of said heat sink that is said electrical bus by a metallic material that melts to flow across and wet said surface of said heat sink and said semiconductor component, thereby bonding said semiconductor component to said heat sink so that said semiconductor component is electrically and thermally coupled to said heat sink.
