Abstract

894,739. Zone-melting. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 25, 1961 [Jan. 28, 1960], No. 2941/61. Drawings to Specification. Class 32. In the formation of a monocrystalline rod of silicon having a protective film of silicon monoxide by zone-melting in an atmosphere comprising oxygen, a molten zone is passed from one end of the polycrystalline rod into a monocrystalline seed joined to the other end and back to the first mentioned end. The rod may be supported in a crucible or at each end only. The passage of the molten zone in the first direction may be through a gas-liquid surface layer, the cross-sectional area of the zone being gradually increased to its maximum within the seed on reversal of direction. Heating may be by a surrounding induction coil. Initial formation of the molten zone at the end of the polycrystalline rod spaced from the seed ensures that irregularities in the initially formed silicon monoxide film affect one end only of the resulting monocrystalline rod, which end may be cut off from the rest of the rod.
