1,044,904. Semi-conductor device. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. July 10, 1963 [July 11, 1962], No. 27418/63. Heading H1K. A semi-conductor device having a particular characteristic is marked for later recognition by passing a current pulse through it to cause a visible change in its surface. In the embodiment diffused planar transistors produced in a common semi-conductor slab are electrically tested using a whisker electrode and defective ones scorched by passing a suitable current pulse through the whisker. The slab, previously scribed, is then broken up into individual devices. |
