Abstract

1282363 Semi-conductor device manufacture SIEMENS AG 29 June 1970 [30 June 1969] 31367/70 Heading H1K Diffusion of impurity into a semi-conductor wafer is effected within an open-ended tube of semi-conductor material with walls at least 5 mm. thick. The tube, preferably made of the same material as the wafer, may be outwardly flared at both ends and fitted with quartz plugs through which the diffusant gas enters and leaves. The tube can be made by boring out a rod of monocrystalline silicon or by deposition from a gaseous compound of silicon on to a carrier which is subsequently removed, and when appropriately doped is provided with terminal electrodes so that it can function as a resistance heater or with a metallic ring for inductive heating by a surrounding coil. Alternative materials specified for the tube are the carbides of silicon, tungsten and titanium, gallium arsenide, indium phosphide, boron nitride and germanium. Specified donor doping diffusant gases are phosphorus pentoxide and trichloride, phosphine, and phosphonitrylic chloride, in argon or other inert carrier gas.
