Latest Patents

Itoh's most recent patents showcase his expertise in silicon carbide barrier technologies and crystal growth methods. One notable patent involves a silicon carbide barrier between a silicon substrate and a metal layer. This approach leverages the unique properties of silicon carbide, which exhibits a slow diffusion rate of metals, thereby preventing unwanted interactions between the metal layer and the silicon substrate. This innovation can be crucial for enhancing the reliability and performance of semiconductor devices.

Another significant patent is the method of growing a single crystalline beta-SiC layer on silicon. In this process, a silicon substrate is placed in a reactor chamber, where it is evacuated and maintained at a reduced atmospheric pressure. The substrate is heated and exposed to a mixed gas containing acetylene, enabling the growth of a buffer layer of carbonized silicon before transitioning to a hydrocarbon and chlorosilane gas mixture for the growth of a thick beta-SiC layer. This method not only enhances the quality of the SiC layer but also has potential implications in various electronic applications.
