Latest Patents

Morishita's patent, titled "Liquid encapsulation method for growing single semiconductor crystals," introduces a novel technique for producing high-quality semiconductor crystals. The method involves melting a semiconductor compound in the presence of a B₂O₃ liquid encapsulant, creating a two-phase liquid. A semiconductor seed crystal is then dipped into this compound melt, which is covered with the B₂O₃ encapsulant. The process allows for the controlled growth of the crystal by pulling up and rotating the seed crystal while maintaining a uniform temperature distribution in the cooling zone. This innovative method results in substantially crack-free semiconductor crystals, both before and after grinding and cutting, with a significantly lower etch pitch density compared to conventionally produced materials.
