| titleOfInvention | A preparation device and method for improving the quality of seed crystals |
| abstract | The present application discloses a preparation device and method for improving the quality of seed crystals. The device includes: a processing chamber, a crucible is arranged in the processing chamber, and the crucible is used to hold raw materials; a heating unit is provided with At the periphery of the crucible, it is used to melt the raw material into a molten state component and sublimate to the seed crystal to repair or reconstruct the atomic steps of the growth surface of the seed crystal; the upper edge of the heating unit does not exceed The liquid level of the molten component; a loading unit, the loading unit is used to load the seed crystal so that the seed crystal is located above the liquid level of the molten component. The preparation device can repair the damaged steps of the seed crystal growth surface, or reconstruct new steps on the seed crystal growth surface, and can simply and efficiently control the step density of the seed crystal growth surface, that is, realize the information of the seed crystal growth surface. It can be repaired or adjusted, laying the foundation for the subsequent growth of ultra-high-quality crystals. |
