PURPOSE:To raise the velocity of growth, by placing a growing solution in a first zone of temperature and placing a growing substrate in a second zone of temperature lower than the former temperature. CONSTITUTION:A substrate 1 is supported on a fixed section 2. A growing solution 3 is contained in a movable section 4. These sections are placed in a furnace so that the sections are set under a temperature distribution as shown in Fig. (b). After a prescribed time, the growing solution 3 is brought into contace with the substrate 1 to cause growth. |
