发明名称 Power semiconductor device
摘要 In a pressure-contacted power semiconductor device, a series of metallization layers provide a pressure-contacting electrode comprising a titanium layer upon a semiconductor body, and a copper layer over the titanium layer. To prevent oxidation of the surface of the copper layer at least one additional metallization layer is arranged over the copper layer.
