Latest Patents

Kotanshi holds a patent for a method of producing single-crystal silicon carbide. This method involves forming a (111) cubic silicon carbide single-crystal layer on a (111) silicon wafer, which is subsequently removed. The resulting single-crystal layer is placed in a graphite crucible to serve as a seed crystal. Silicon carbide source material powder is sublimated in an inert gas atmosphere, while maintaining a lower temperature for the single-crystal layer compared to the source material. This process allows for the formation of a (0001) α-type silicon carbide single-crystal layer with large diameter and high quality at a low cost. He has 1 patent to his name.
