Interest in germanium tetrafluoride and decaborane as ion implant source materials is increasing. Both of these materials are considered to be extremely toxic, however applicable toxicological literature is limited. EHS evaluation of these materials is complicated by the lack of direct sampling techniques and the potential complex chemical reactions taking place in the ion source. This presentation will focus on methods of evaluating the EHS considerations in handling the materials, and operating and maintaining the equipment. Recommended safety precautions and exposure monitoring techniques will be included.
