Publication number: 20240145583Abstract: A method for manufacturing a SONOS memory discloses forming first 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. An lightly doped drain (LDD) implantation area is defined by a lateral thickness of a thin oxide layer, so that the channel width may be controlled by controlling the thickness of the thin oxide layer. Thus, the width of a current channel at the bottom of a gate is reduced under the same ion implantation condition into the active area, thereby improving a current capacity of the SONOS memory without adding any mask or photolithography step, and thus bring no additional patterning costs or active area ion implantation costs.Type: ApplicationFiled: July 28, 2023Publication date: May 2, 2024Inventors: Tianquan SHI, Zhenghong LIU, Ruisheng QI, Haoyu CHEN
