A method for fabricating a heat sink including providing a carbon metal composite having a plurality of metal-coated carbon fibers and a plurality of openings, the openings leading from a first side of the carbon metal composite to a second side of the carbon metal composite, disposing the carbon metal composite over a semiconductor element such that the first side of the carbon metal composite faces the semiconductor element, and bonding the carbon metal composite to the semiconductor element by means of an electroplating process, wherein a metal electrolyte is supplied to an interface between the carbon metal composite and the semiconductor element via the plurality of openings.
