Latest Patents

Zhonglin Han holds a patent for a method for oxidizing silicon carbide based on microwave plasma at an AC voltage. This method involves several steps: first, providing a silicon carbide substrate and placing it in a microwave plasma generating device. Next, oxygen-containing gas is introduced to generate oxygen plasma at an AC voltage. The AC voltage controls the movements of oxygen ions and electrons in the plasma, allowing for the generation of an oxide layer with a predetermined thickness on the silicon carbide substrate. When the substrate voltage is negative, oxygen ions move close to the interface to perform an oxidation reaction. Conversely, when the voltage is positive, electrons move close to the interface to perform a reduction reaction, effectively removing carbon residue. The process concludes by stopping the introduction of oxygen-containing gas and halting the reaction completely.
