Latest Patents

Ruisheng Qi holds a patent for a "Method for manufacturing SONOS memory." This patent discloses a process that involves forming a thin oxide layer as a sidewall protection layer and a blocking layer. This layer prevents the high dielectric-constant layer at the bottom of the stacked gate structure from being exposed on the surface. The method allows for the definition of a lightly doped drain (LDD) implantation area by controlling the lateral thickness of the thin oxide layer. Consequently, the width of the current channel at the bottom of the gate is reduced under the same ion implantation conditions, thereby enhancing the current capacity of the SONOS memory without incurring additional patterning costs or active area ion implantation costs.
