Patent ID: 7271034

Claim:
A method for fabricating a semiconductor device, the method comprising the steps of: providing a carrier having a seed layer; providing a patterned mask layer on the seed layer of the carrier, said patterned mask layer having a recess structure; depositing a thermally conducting material on the patterned mask layer in the recess structure, thus forming structure elements of a thermally conducting structure; depositing a solder on the thermally conducting structure; removing the patterned mask layer and the seed layer between the structure elements of the thermally conducting structure; attaching the thermally conducting structure to a surface of a semiconductor device via soldering; providing the carrier in a form of a transparent substrate coated with a polyimide layer, said seed layer being formed on top of the polyimide layer; removing the carrier; and attaching a manifold layer to the thermally conducting structure attached to the surface of the semiconductor device.
