Abstract
A cooling system for a semiconductor device. The system includes a first heat sink containing a ceramic material as a main component and a semiconductor device having a first contact surface. The first heat sink serves for cooling the semiconductor device and as an electrical insulator with respect to the semiconductor device. Furthermore, a first metal-containing layer is provided on at least one outer surface of the first heat sink, the first metal-containing layer having a size at least equal to the area of the first contact surface of the semiconductor device. The semiconductor device is attached to the first metal-containing layer via the contact surface by a first bonding layer formed by soldering or sintering.
