Abstract

1467860 Monocrystalline semiconductor rods PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 23 Dec 1974 [28 Dec 1973] 55383/74 Heading B1S In the manufacture of rods of monocrystalline semiconductor compounds e.g. GaAs, by reacting a component thereof in the vapour phase with component thereof in the liquid phase to form a molten reaction product in a boat of SiO 2 , containing a monocrystalline seed crystal, followed by cooling, the reaction product is firstly solidified and then re-melted prior to the cooling step. GaAs rods may be prepared by heating Ga 7 in an SiO 2 boat 6 to a temperature of 1260‹C and As 4 to a temperature of 610‹C in a sealed SiO 2 tube 1, the inner surface of which has been roughened by sandblasting and/or etching with HF. Following wetting of the seed crystal 8 by the molten reaction product the boat is cooled to 1230‹C over a period of 1 hr. Subsequently the boat is re-heated to 1260‹C in 1 hr and then allowed to cool to 1200‹C in 10 hrs, progressive cooling being used so that the solidification starts at the seed-end.
