Latest Patents

Onda holds a patent for a "Method and apparatus for producing silicon carbide crystal." This patent describes a technique to produce SiC crystals in a shape suitable for use as wafers. The method involves placing a guide around a SiC crystal substrate to control the growth direction of the crystal. By adjusting the temperature of the guide to be higher than the sublimation temperature of SiC, Onda's method effectively restricts the growth of the crystal, allowing for precise shaping. When the guide is formed in a hexagonal tube shape, the resulting SiC crystal can be produced in a hexagonal pole shape, aligning with specific directions of the SiC crystal substrate.
