Latest Patents

Kanai's latest patents include a nitrogen-doped n-type SiC-formed material and a method for manufacturing this material. The nitrogen-doped SiC-formed material consists of high purity β-type crystals, which exhibit low resistivity and low light transmittance. This makes it suitable for use as a substrate in semiconductor fabrication devices. The manufacturing method involves a chemical vapor deposition (CVD) process, where nitrogen gas is introduced alongside raw material gases to form a SiC film on a substrate. The resulting material has a specific gravity of 3.15 or more, light transmittance ranging from 1.1% to 0.05%, and resistivity of 3×10^10 Ω·m.

Another notable patent focuses on the fabrication of SiC films with excellent strength and thermal characteristics. These films are produced through a CVD process and demonstrate thermal conductivity between 100 and 300 W/m·K, with an average grain diameter of the internal structure ranging from 4 to 12 micrometers. The thermal conductivity ratio along the direction of SiC crystal growth to that in the perpendicular direction is ideally between 1.10 and 1.40.
