Latest Patents

One of his latest patents is titled "CVD-based process for manufacturing stable low-resistivity poly-metal gate electrodes." This patent describes a process for forming a W-poly gate stack, which includes several steps: the deposition of doped polysilicon on a thin dielectric layer covered substrate, the deposition of WNx by a CVD-based process, thermal treatment to convert WNx into a thermally stable barrier (WSiNx), and the deposition of a W layer. The stack layers are then etched to form the gate electrode.

Another significant patent is "Stacked insulating film including yttrium oxide." This invention discloses a capacitor and a method for making the same, wherein one plate of the capacitor comprises silicon. The dielectric material includes a silicon nitride layer adjacent to the silicon plate, and a layer of yttrium oxide disposed thereover. The second plate of the capacitor is formed over the yttrium oxide layer. The silicon nitride provides a barrier to the diffusion of silicon into the yttrium oxide film when heated, resulting in a high dielectric constant capacitor dielectric with improved leakage characteristics.
