Latest Patents

One of Jie Wei's latest patents is titled "Polarization-doped enhancement mode HEMT." This invention pertains to semiconductor technology and involves a polarization-doped enhancement mode HEMT device. The technical solution includes the sequential growth of the first and second barrier layers with gradient Al composition on a buffer layer. The gradient trends of these layers are opposite, leading to the generation of three-dimensional electron gas (3DEG) and three-dimensional hole gas (3DHG) in the barrier layers due to inner polarization differences. A trench insulated gate structure is positioned away from the metal drain and in contact with the source, significantly improving the on-state current due to the presence of highly concentrated electrons in the first barrier layer. Additionally, the vertical conductive channel between the source and the 3DEG is pinched off by the 3DHG, achieving the enhancement mode.

Another significant patent is the "Enhancement mode high electron mobility transistor." This invention includes a substrate layer, buffer layer, barrier layers, drain electrodes, reverse polarization semiconductor layers, source electrodes, an insulated gate dielectric, and a metal gate electrode. The buffer layer is placed on the substrate layer, with barrier layers on top. The interfaces between the buffer layer and barrier layers feature first heterojunctions that create a two-dimensional electron gas (2DEG) channel. The drain electrodes are located at one end of the upper surfaces of the barrier layers, forming Ohmic contact. The reverse polarization semiconductor layers on the barrier layers produce inversed polarization, with second heterojunctions providing a two-dimensional hole gas (2DHG).
