Latest Patents

Among his latest patents are innovations such as the silicon nitride sintered body, silicon nitride substrate, and silicon nitride circuit board. The silicon nitride sintered body includes silicon nitride crystal grains and a grain boundary phase, where dislocation defect portions exist inside at least some of the silicon nitride crystal grains. Notably, a percentage of the silicon nitride crystal grains among any 50 of them must have completely visible contours in any cross section or surface of the sintered body, ranging from 50% to 100%. Furthermore, the silicon nitride substrate, which utilizes the silicon nitride sintered body, is designed with a plate thickness between 0.1 mm and 0.4 mm. The TCT characteristics can be enhanced by employing the silicon nitride substrate in the silicon nitride circuit board. Additionally, the sintered body comprises a crystal grain containing silicon nitride and a grain boundary phase, with dielectric losses measured while applying an alternating voltage across a frequency range from 50 Hz to 1 MHz.
