Abstract
1310806 Semi-conductor devices SIEMENS AG 19 April 1971 [19 March 1970] 24818/71 Heading H1K In the manufacture of a transistor including a diffused emitter region 3, the emitter electrode 11 is only applied to the region 3 after the base electrode 7 has been applied and alloyed or sintered to the surface of the base region 2. The emitter electrode 11 is itself not alloyed to the emitter region 3. The surface of the emitter region 3 is preferably protected during alloying of the base electrode by the thin oxide coating resulting from the emitter diffusion, the emitter electrode 11 eventually being applied in the reopened emitter diffusion window 9. Both emitter and base electrodes may be connected to conductive paths or screening layers 8, 12. Suitable materials for the base electrode 7 are Al and/or Pt while the emitter electrode 11 may be made of Ti, Zr, Cr, Ni, Mo, Ti/Al mixture or double layers of Ti/Al, Ti/Au or Ti/Ag.
