20110203515Device for crystal growth at intermediate temperatures using controlled semi-active cooling - A crystal growing cell which has computerized temperature control and agitation means to inhibit crystal nucleation. The temperature is controlled semi-actively, i.e., by monitoring the temperature with a thermistor and balancing ambient heat loss with heat added to the system by heating resistors or heating elements. When the chemical is completely dissolved by heating the mixture to a temperature above the saturation temperature, the temperature is lowered. At the saturation temperature the temperature is initially reduced slowly to avoid crystal nucleation. The saturation temperature of the initial solution is selected to be at an intermediate temperature which is high enough that the amount of dissolved material is large enough to produce a large crystal or large crystal clusters, yet not so high that the solubility curve has a large slope and therefore requires a high degree of temperature control to avoid crystal nucleation in the solution. Use of the cell with a variety of chemical solutions, each having the same saturation temperature, facilitates optimization while maintaining a simple, low cost design.08-25-2011

20080295763Apparatus for manufacturing Group III nitride semiconductor and method for manufacturing Group III nitride semiconductor - A Group III nitride semiconductor crystal is grown according to a flux method. After completion of the crystal-growing process, Na is discharged from a crucible by a recovery device when the temperature of the crucible is 100° C. or higher, and is held in a holding vessel in a liquid state. The recovered Na can be drawn from the holding vessel via a faucet. Na remaining after completion of the crystal-growing process does not contain impurities of high vapor pressure, and is thus of high purity. Therefore, reuse, as flux, of the recovered Na enables manufacture of a Group III nitride semiconductor whose concentration of impurities is low.12-04-2008
