Latest Patents

Mishima's latest patents revolve around silicon carbide single crystal substrates. One of his notable inventions involves a sophisticated measurement technique utilizing X-rays. In his innovation, when a detector is positioned in the [11-20] direction, the first measurement region, which includes the center of the main surface, is exposed to X-ray irradiation within a ±15° variation relative to the [-1-120] direction. This method achieves a maximum intensity ratio of more than or equal to 1500. Additionally, when the detector aligns with a direction parallel to the [-1100] direction and the measurement region is irradiated within a ±6° variation relative to the [1-100] direction, the maximum intensity ratio of a second intensity profile similarly reaches or exceeds 1500. This advancement significantly improves the precision of energy difference measurements, stating that an absolute value of the difference between the maximum and minimum energy that yields the maximum value in the first intensity profile remains less than or equal to 0.06 keV.
