AB - New insight into the mechanism for the changes in silicon with solid‐state heat treatment has been obtained with the aid of the floating zone apparatus normally used to refine silicon. With this system, a liquid or solid hot zone may be caused to traverse the rod while the rest of the apparatus is kept relatively cool.Through the use of this technique, it has been established that contaminants left on the silicon surface even after careful etching and washing procedures are a controlling factor in the observed heat treating effects. The impurities involved have high diffusivities, as is the case for copper and iron in silicon. That these impurities lower lifetime on heat treatment has been demonstrated by rubbing the silicon rod with copper or iron wires prior to zone heat treatment.
