Latest Patents

Among his latest innovations, Dai has developed a patented method titled "Hydroxyl group termination for nucleation of a dielectric metallic oxide." This invention outlines a process where a semiconductor-containing dielectric material or oxynitride/nitride surface is treated with a basic solution, resulting in hydroxyl group termination of the surface. Following this treatment, a dielectric metal oxide is deposited through atomic layer deposition. This technique ensures a uniform surface condition that facilitates nucleation and minimizes interfacial defects. Furthermore, the treatment enhances the removal of oxide from silicon germanium alloy surfaces with higher germanium concentrations, reducing thickness variations across differing compositions.

Another notable patent focuses on "Field effect transistors having multiple effective work functions." In this innovation, selective deposition of a silicon-germanium surface layer on semiconductor surfaces enables the formation of two distinct channel regions for field effect transistors. By annealing an adjustment oxide material on a combination of silicon-based and high-k gate dielectrics, Dai's approach induces oxygen deficiency in specific portions of the high-k layer. This selective modification allows for the deposition of multiple work function metallic materials, resulting in gate electrodes that exhibit various effective work functions.
