Latest Patents

One of his latest patents is titled "Method of fabricating sub-micron gate electrode by angle and direct." This patent discloses a method for fabricating semiconductor devices with sub-micron gate electrodes using angle and direct evaporation techniques. The process involves forming a first and second photoresist layer atop a substrate, selectively processing the second layer to create a well-controlled profile, and evaporating a first metal at a specific angle. The edge of the second photoresist layer shields part of the first photoresist layer from metal deposition, defining a patterned opening of desired width. The method allows for precise etching to expose a portion of the active channel region, ultimately leading to the formation of a gate electrode with a defined gate length.

Another significant patent is the "Method of fabricating group III-V compound." This invention describes a solution of hydrogen peroxide, citric acid, and a salt of citric acid that selectively etches GaAs-containing Group III-V compounds. The etchant solution operates within a specific pH range, allowing for the selective etching of materials like AlGaAs in the presence of other compounds. This method is particularly useful in the fabrication of high-frequency transistors, enhancing their performance characteristics.
