Publication number: 20240096986Abstract: A method includes forming a first gate spacer and a second gate spacer on a sidewall of a first gate structure. The first gate spacer is between the second gate spacer and the first gate structure. A first interlayer dielectric (ILD) layer is formed to surround the first gate spacer, the second gate spacer, and the first gate structure. A portion of the second gate spacer and a portion of the first ILD layer are removed simultaneously. A top surface of the second gate spacer is lower than a top surface of the first ILD layer.Type: ApplicationFiled: December 1, 2023Publication date: March 21, 2024Applicant: TAIWAN SEMICONDUCTOR MANUFACTURING CO., LTD.Inventors: Chung-Ting LI, Jen-Hsiang LU, Chih-Hao CHANG
