Patent number: 11923429Abstract: A semiconductor device and method for forming the semiconductor device are provided. In some embodiments, a semiconductor substrate comprises a device region. An isolation structure extends laterally in a closed path to demarcate the device region. A first source/drain region and a second source/drain region are in the device region and laterally spaced. A sidewall of the first source/drain region directly contacts the isolation structure at a first isolation structure sidewall, and remaining sidewalls of the first source/drain region are spaced from the isolation structure. A selectively-conductive channel is in the device region, and extends laterally from the first source/drain region to the second source/drain region. A plate comprises a central portion and a first peripheral portion. The central portion overlies the selectively-conductive channel, and the first peripheral portion protrudes from the central portion towards the first isolation structure sidewall.Type: GrantFiled: August 18, 2021Date of Patent: March 5, 2024Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Chih-Chang Cheng, Fu-Yu Chu, Ming-Ta Lei, Ruey-Hsin Liu, Shih-Fen Huang
