Latest Patents

Tongjun Yu holds a patent for a "Patterned aluminum nitride composite substrate and preparation method thereof." This invention provides a patterned aluminum nitride (AlN) composite substrate and a method for its preparation. The process involves creating a single crystal AlN with a semi-suspended structure on a high temperature-resistant substrate. The design features a non-suspended AlN covered by an optical medium material, while a suspended AlN is left exposed. This configuration allows for a surface with low dislocation density and low mismatch stress, which serves as a nucleation growth zone for nitride semiconductors. The result is a patterned AlN composite substrate that improves the epitaxial interface between the nitride semiconductor and the AlN.
