Publication number: 20240088269Abstract: In a method of manufacturing a semiconductor device, a fin structure having a bottom part and an upper part on the bottom part is formed over a substrate. The bottom part is trimmed so that a width of an uppermost portion of the bottom part is smaller than a width of the upper part. Bottom end corners of the upper part are trimmed to reduce a width of the upper part at a bottom of the upper part. An isolation insulating layer is formed so that the upper part protrudes from the isolation insulating layer. A dummy gate structure is formed. A source/drain structure is formed. An interlayer dielectric layer is formed over the dummy gate structure and the source/drain structure. The dummy gate structure is replaced with a metal gate structure.Type: ApplicationFiled: November 22, 2023Publication date: March 14, 2024Applicant: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Jiun Shiung WU, Guan-Jie SHEN
