    • This invention relates to a method for direct solidification of semiconductor grade multi-crystalline silicon ingots allowing improved control with the solidification process and reduced levels of oxygen and carbon impurities in the ingot, by crystallizing the semiconductor grade silicon ingot, optionally also including the melting of the feed silicon material, in a crucible made of silicon nitride, or in a crucible made of a composite of silicon carbide and silicon nitride, and where the wall thickness of the bottom of the crucible is dimensioned such that the thermal resistance across the bottom is reduced to a level of at least the same order as thermal resistance across the support below carrying the crucible or lower. The invention also relates to crucibles which are made of silicon nitride, or of a composite of silicon carbide and silicon nitride, and where the wall thickness of the bottom of the crucible is dimensioned such that the thermal resistance across the bottom is reduced to a level of at least the same order as thermal resistance across the support below carrying the crucible or lower.

    • Apparatus for forming a multiplicity of thin wafers from at least two similar blocks, the apparatus comprising a supply reel (1) to supply wire, an upper pair (3a, 3b) and a lower pair (3c, 3d) of parallel spaced roller guides and a collection reel (4); a wire from the supply reel passes around successive grooves along the roller guides from near the supply reel to near the collection reel, so to form a four sided continuous web of wires along the length of the roller guides. Part way along the roller guides, the wire is diverted around at least two pulley wheels (5a, 5b) removing the wire from the web after it has passed over a roller guide at a predetermined point, and reintroducing the wire into the web via a subsequent roller guide at a point laterally displaced from the point at which it left the web, so that there is a gap in the web of wire which divides the web into two separate sections, and no cutting action can occur in that gap. ® KIPO & WIPO 2007
