1,248,164. Crystal-pulling. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 15 Jan., 1969 [18 Jan., 1968], No. 2416/ . 69. Heading B1S. In the crystal-pulling of a compound from a solution, the compound is replenished by absorption in the solution at a position separated from the crystal-pulling surface of (a) a preformed crystal of the compound, (b) the separate components, or (c) at least one non- volatile component, the solvent comprising at least one non-volatile component (with reaction in solution in (b) and (c). The compound may be the arsenide or phosphide of gallium or gallium/indium, or the arsenide/phosphide of gallium. Arsenic may be supplied as hydride or halide. A volatile component may be absorbed through a porous wall 8 (Fig. 1) or into upper surface 29 separated from the crystal-pulling upper surface 44 by a downwardly extending partition 30 (Fig. 2). In a modification of the latter (not shown), a porous wall separating upper surface 28 from the volatile compound replaces wall 28. |
