Abstract
869,863. Semi-conductor devices. FELL Ltd., A & M. June 10, 1959 [June 18, 1958], No. 19462/58. Class 37. In a method of alloying activator material to a semiconductor during the manufacture of a rectifier diode or transistor a pellet of the material is located in contact with the semi-conductor by a real or synthetic jewel jig. In one embodiment (Fig. 3) a pellet 1 of indium is placed in the cavity formed by the annular and flat jewels 4b, 4a beneath a germanium wafer 6, and a second indium pellet 8 dropped into the aperture of a third jewel 8. The jewels, which may consist of ruby, sapphire, spinel, zircon, or rutile are located in steel shanks 5, 7 by spinning the bevelled edges of the shanks over the corresponding bevelled edges of jewels 4b, 8. The annular and flat jewels 4b, 4a may be replaced by a single jewel with a hemispherical or conical cavity in its upper face. Alloying is effected by passing the assembly through an oven. As an alternative a single pellet is first alloyed to the upper face of the wafer in an assembly in which the lower jewel or jewels are replaced by a plane surfaced jewel, whereupon the wafer is inverted and a second pellet alloyed to the now uppermost face. The advantage of using jewels for the jigs is that they can be machined with greater precision than other refractory materials.
