Latest Patents

Among his latest patents is a remarkable preparation method for semiconductor structures. This invention focuses on the creation of an innovative semiconductor structure that includes a substrate, an epitaxial layer, and an epitaxial structure arranged in sequence. Importantly, the epitaxial layer is doped with a specific doping element. During the forming process, a sacrificial layer is introduced on the epitaxial layer, which is then subjected to repetitive etching. This process ensures that the concentration of the doping element within the epitaxial layer remains below a designated threshold, effectively preventing the upward precipitation of the doping element into the upper-layer structures. This invention is designed to enhance the mobility of electrons in the channel layer, thereby improving the overall device performance.

Another significant patent addresses the development of a heterostructure that involves alternating sets of channel and barrier layers. This semiconductor structure includes a heterojunction with at least two sequentially stacked sets of channel and barrier layers. It features a first p-type semiconductor situated in the gate region of the heterojunction, extending to its base, and a second p-type semiconductor placed over the gate region. This design enables the realization of a multilayer two-dimensional electron gas (2DEG) through the strategic use of multilayer channel and barrier layers, enhancing the concentration of 2DEG and reducing resistance. The first p-type semiconductor in the gate region also helps to deplete the 2DEG for normally-off operation, thus increasing the threshold voltage.
