Latest Patents

Yutaka Itoh holds a patent titled "Method for preparing silicon carbide single crystal." This innovative method involves the production of SiC single crystals through a solution growth approach where a seed crystal is immersed in a SiC solution dissolved in a melt of silicon or a silicon alloy. The growth process is optimized by gradually cooling the solution or introducing a temperature gradient. A notable aspect of this method is the accelerated rotation of the crucible, which is carefully controlled to improve crystal growth rates. By reversing the rotational direction during the process and potentially synchronizing the seed shaft's rotation, Itoh's technique enables the creation of large, high-quality single crystals free of inclusions.
