Patentanspruch:Claim:Verfahren zum Herstellen von Transistoren, insbesondere Hochfrequenztransistoren, durch Legieren,
bei dem die Erwärmung auf die Legierungstemperatur möglichst rasch und die Abkühlung
nach Erreichen der Legierungstemperatur zunächst langsamer und dann schneller erfolgt, dadurch
gekennzeichnet, daß der rasche Anstieg bis zur Legierungstemperatur nach einer Funktion
dritten Grades in einer Temperaturzone erfolgt, deren Temperatur über der Legierungstemperatur
liegt, und daß nach Erreichen der Legierungstemperatur bis zu einer oberhalb des Erstarrungspunktes
liegenden Abkühlungstemperatur zunächst langsam nach einer linearen Funktion und von dieser
Abkühlungstemperatur bis zur Erstarrungstemperatur beschleunigt nach einer e-Funktion abgekühlt
wird.Process for producing transistors, in particular high-frequency transistors, by alloying,
in which the heating to the alloy temperature as quickly as possible and the cooling
after the alloy temperature has been reached, it takes place initially more slowly and then more quickly, as a result
characterized in that the rapid rise up to the alloy temperature according to a function
third degree takes place in a temperature zone whose temperature is above the alloy temperature
is, and that after reaching the alloy temperature up to one above the solidification point
lying cooling temperature initially slowly according to a linear function and from this
Cooling temperature up to the solidification temperature accelerated after an exponential function
will.
