Publication number: 20250107170Abstract: Methods for isolating two adjacent transistors are disclosed. A substrate has a first semiconducting fin on a first region and a second semiconducting fin on a second region, and the first semiconducting fin and the second semiconducting fin contact each other at a jog region. A dummy gate within or adjacent the jog region is removed to expose a portion of the first semiconducting fin and form an isolation volume. Etching is performed to remove the exposed portion of the first semiconducting fin and create a trench in the substrate. The trench and the isolation volume are filled with at least one dielectric material to form an electrically isolating structure between the first region and the second region. Additional dummy gates in each region can be removed and replaced with an electrically conductive material to form two adjacent transistors electrically isolated from each other.Type: ApplicationFiled: September 25, 2023Publication date: March 27, 2025Inventors: Yun-Chen WU, Tzu-Ging LIN, Jih-Jse LIN, Jun-Ye LIU, Chun-Liang LAI, Chih-Yu HSU
