Abstract:
1. A method for fabricating a semiconductor device, the method comprising the steps of: forming a thermally conducting structure on a carrier, said thermally conducting structure comprising a plurality of structural cooling elements of a high aspect ratio selected from a group consisting of: an array of freestanding fins, studs, and frames, and a grid of connected fins; mounting semiconductor chips on an upper surface of a substrate; coating backsides of the semiconductor chips with an adhesion layer; removing the carrier; attaching a manifold layer comprising the thermally conducting structure to the backside of the semiconductor chips via solder balls to obtain a multi-chip module, wherein said manifold layer comprises fluid inlets and outlets; and sealing the manifold layer to the semiconductor chips by melting the solder balls with the adhesion layer, such that the thermally conducting structure becomes attached to the adhesion layer.
