Latest Patents

Guo's patent, titled "Method for Passivating Silicon Carbide Epitaxial Layer," focuses on a technique that improves the quality of silicon carbide used in electronics. The method involves introducing a carbon source and silicon source into a reaction chamber to grow a silicon carbide epitaxial layer on a substrate. Following this, the carbon source is turned off, and a nitrogen source along with silicon is introduced to grow a silicon nitride thin film on the upper surface of the silicon carbide layer. This innovative approach results in a thin film with few defects and high quality, making it suitable as a lower dielectric layer of a gate electrode in field effect transistors. Notably, Guo’s method eliminates the need for an additional oxidation process to form a SiO dielectric layer, thus streamlining device fabrication procedures.
