Abstract

A point contact electrode suitable for use in a semi-conductor device (see Group XXXVI) is made of a metal which has been coated with aluminium by heating in contact with aluminium powder in a non-oxidizing atmosphere. In the embodiment electrode wires of platinum or tungsten are heated in a mixture of 10-20 per cent aluminium powder with alumina at 400-600 DEG C. for 4 to 6 hours and preferably heated for a similar period at 800-1000 DEG C. after withdrawal from the mixture to diffuse the aluminium uniformly through the metal.
