Abstract

911,292. Semi-conductor devices. MULLARD Ltd. Jan. 14, 1959 [Jan. 16, 1958], No. 1561/58. Class 37. In the manufacture of a semi-conductor device, material is alloyed to the semi-conductor over an area, a narrow channel is cut in the resolidified alloying material extending at least to the recrystallized semi-conductor region, and then the assembly reheated to realloy the separate parts to the semi-conductor. Fig. 2 shows a P-type germanium crystal 1 to which an alloy of lead and 1% antimony was alloyed by heating in hydrogen at 700‹ C. for 3 minutes to form N-type regions 2a and 2b. Regions 3a, and 3b consist of resolidified lead and antimony and regions 5 consist of a thin N-type layer, beyond the interface produced by diffusion of the antimony during the alloying process. Slot 6 is then cut into region 1, for example by ultrasonic means with a slurry of aluminium oxide abrasive or by reciprocating a thin wire with abrasive, and the assembly then etched with hydrogen peroxide. Before or after etching, region 3b is coated by vacuum deposition or by means of a dispersion, with aluminium and the whole then heated for 10 minutes at 750‹ C. This results in the formation of P-type region 9b (Fig. 3), and a further N-type 9a region by an alloying process and the extension of the antimony diffused layer to form a well defined and extended N-type layer 12, since antimony diffuses more than aluminium. The lower portion below line 13 is then removed by an etching process and an alloy of indium and 1% gallium is alloyed to this region to form an ohmic contact 15 to the P- type region 1. Nickel wires 16, 18 and 19 (Fig. 5), are soldered to metallic regions 15, 3a and 3b to form the collector, base and emitter electrodes respectively of a transistor, the N- type diffused layer 12 constituting the base zone. While slot 5 is protected with a polystyrene layer, the device is electrolytically etched to remove part of the layer 12 and undercutting regions 3a, 3b and 15. The resulting transistor has low base resistance since base region 3a is near emitter region 3b, and low interelectrode capacitance. In an alternative arrangement, the electrodes are annular shaped. The semi-conductor material may consist of germanium, silicon, GaAs, InP or other AIII BV compound. Tin and bismuth may be used in place of lead. The invention may also be applied to a diode or a field effect transistor, and the semi-conductor may be poly- or mono-crystalline.
