Claim 1
Independent Claim
84 words
A METHOD FOR PRODUCING AN ELECTRODE-CARRYING SEMICONDUCTOR DEVICE IN WHICH THE SEMICONDUCTOR IS COMPOSED OF SILICON, COMPRISING FORMING AT LEAST ONE ELECTRON OF FOIL THICKNESS ON A SILICON MONOCRYSTAL BY ALLOYING INTO SAID SILICON MONOCRYSTAL A QUANTITY OF GOLD CONTAINING FROM 0.2% TO 5% ANTIMONY AND A TRACE CONTENT OF SULPHUR TO FORM A JUNCTION ZONE LARGER THAN 1 MM.2 IN AREA, SAID ELECTRODE HAVING AN AREA EQUAL TO THAT OF SAID JUNCTION ZONE, WHEREBY FAULTY ALLOYING SPOTS IN SAID JUNCTION ZONE ARE MINIMIZED.
