Abstract (en)

[origin: DE19506323A1] A semiconductor device has a semiconductor body of which at least part of the non metallised contact surface is roughened. The metallised contact layer is made of a base metallic material such as aluminium. A process that does not attack the metallised contact surface is used to roughen the semiconductive surface.
