THE METHOD OF MAKING OHMIC CONNECTION TO A BODY OF SILICON WHICH COMPRISES: (A) COATING SURFACE PORTIONS OF SAID BODY, TO WHICH CONNECTION IS TO BE MADE, WITH AN OVERLAY OF GERMANIUM; (B) COATING MATING SURFACE PORTIONS OF A CONNECTING MEMBER WITH A METAL SELECTED FROM THE GROUP CONSISTING OF GOLD AND LEAD; (C) PLACING SAID COATED SURFACE PORTIONS IN CONTACT; (D) HEATING THE ZONE OF JUNCTURE TO A TEMPERATURE ADJACENT THE TEMPERATURE OF THE EUTECTIC FORMED BY SAID METAL AND SAID GERMANIUM; AND (E) COOLING SAID ZONE OF JUNCTURE TO PERMIT FORMATION OF A MECHANICALLY STRONG OHMIC CONNECTION BETWEEN SAID BODY AND SAID MEMBER.
