Abstract
In a cooled high-power semiconductor device, the cooling is improved as a result of the fact that contact filaments (3a,b) which are arranged in brush form and which form cooling channels (11a,b) between them through which a coolant flows make contact with the semiconductor substrate (1) by a materially continuous joint.
