Latest Patents

Duo Cao holds a patent for a "Fluorinated graphene passivated AlGaN/GaN-based HEMT device and manufacturing method." This invention involves an AlGaN/GaN HEMT that utilizes fluorinated graphene passivation, replacing the conventional nitride passivation layer. The process includes transferring monolayer graphene to an AlGaN surface, treating it with fluoride ions, and insulating it. This method allows for the growth of a high-k material on the graphene, which, along with the graphene, serves as a gate dielectric for preparing an AlGaN/GaN metal-insulator-semiconductor (MIS) HEMT. Compared to traditional passivation structures, this innovation offers advantages such as a small physical thickness at the sub-nanometer scale and a low additional threshold voltage. The simplicity of the structure and method, along with its remarkable effects, highlights its wide application prospects in microelectronics and solid-state electronics.
