Patent number: 12628385Abstract: A high voltage transistor may include a stepped dielectric layer between a field plate structure and a channel region of the high voltage transistor in a substrate. The stepped dielectric layer may increase the breakdown voltage of the high voltage transistor by reducing the electric field strength near the drain region of the high voltage transistor. In particular, a portion of the stepped dielectric layer near the drain region includes a thickness that is greater relative to a thickness of another portion of the stepped dielectric layer near the gate structure. The increased thickness near the drain region provides increased electric field suppression near the drain region (which operates at high voltages). In this way, the stepped dielectric layer enables the high voltage transistor described herein to achieve higher breakdown voltages without increasing the distance between the gate structure and the drain region of a high voltage transistor.Type: GrantFiled: April 17, 2023Date of Patent: May 12, 2026Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Kaochao Chen, Chia-Cheng Ho, Chia-Jui Lee, Chia-Yu Wei

Patent number: 12581680Abstract: 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: GrantFiled: July 28, 2023Date of Patent: March 17, 2026Assignee: Shanghai Huali Microelectronics CorporationInventors: Tianquan Shi, Zhenghong Liu, Ruisheng Qi, Haoyu Chen
