Abstract

860,400. PN junction diodes. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 3, 1959 [July 17, 1968], No. 23988/58. Class 37. A PN junction diode is made by alloying donor (acceptor) pellets to opposite sides of a P(N) type semi-conductor (e.g. germanium) body to such a depth as to produce a continuous region of N(P) type material extending between the pellets, and subsequently reducing the area of the PN junction defining the boundary of this region by reducing the thickness of the body at the junctions. In the example (Fig. 3), in which a cylindrical zone 3 is produced by using circular pellets, the junction area is reduced by applying a voltage between the P and N regions and electrolytically etching in a 10% solution of caustic potash. The capacitance of the junction may be continuously measured during etching to allow fine control of the final capacitance.
