Title: Production of single crystal and device therefor
Inventor: NAKAGAWA MASAHIRO
IPC: C30B27/02
Filed: 1985-12-26
Abstract: PURPOSE:To suppress turbulent convection of raw material melt and to grow single crystal of low dislocation density in high yield, by carrying out crystal growth in such a way that the separated position of a first and a second heaters is not made higher than the liquid level of raw material melt. CONSTITUTION:Raw material melt 3 and a liquid sealing agent 4 in a crucible 16 are kept in a melt state by the heat of heaters 1 and 2. In the operation, a separated position Z of the first heater 1 and the second heater 2 is made not lower than melt liquid level W, namely, Z >= W. Since the raw material melt is heated by one heater, no turbulent convection will occur and stable steady convection exists. When seed is immersed, W = Z is kept. When crystal is grown while maintaining height of lower axis constant, the melt liquid level W naturally lowers and correlation W < Z is attained. On the contrary, it is also possible to raise the lower axis and to make the position of solid-liquid interface invariable and the correlation is always W <= Z in this case. High- quality single crystal with low dislocation density can be obtained and single crystal can be grown in high yield.

Abstract: PROBLEM TO BE SOLVED: To provide a processing tank apparatus which does not interfere with the surroundings, for example, of a vacuum processor, opening of a lid of the processing tank can be increased, and degree of freedom in design can be increased. SOLUTION: The processing tank apparatus comprises a processing tank 11 including an opening 11a at an end, a processing tank lid 12 for opening/ closing the opening, a coupling arm 13 with an end fixed to the processing tank lid, a coupling shaft 15 for pivotably coupling the other end of the coupling arm with a tip of a piston 14b of a cylinder apparatus, and an attaching shaft for pivotably pivoting the cylinder apparatus 14. Since the cylinder apparatus 14 is thus placed along the processing tank 11, the processing tank lid 12 is pulled via the coupling arm 13 toward side wall of the processing tank, thereby allowing the lid 12 to be fully opened for the opening 11a. In addition, the cylinder apparatus 14 may not disturb placement of other apparatuses in its periphery, thereby enhancing the degree of freedom in the design.
