Abstract
A semiconductor device includes a first semiconductor structure, a second semiconductor structure, a first isolation block and a second isolation block. The first semiconductor structure includes a first gate structure wrapping around a first sheet structures and a second sheet structures, and a first dielectric wall disposed between and separating the first and second sheet structures. The second semiconductor structure includes a second gate structure wrapping around third sheet structures. The first isolation block is disposed on the first dielectric wall of the first semiconductor structure and separates the first gate structure into a first gate portion wrapping around the first sheet structures and a second gate portion wrapping around the second sheet structures. The second isolation block is disposed between the first and second semiconductor structures and separates the first gate structure from the second gate structure. The first isolation block has an extending depth smaller than an extending depth of the second isolation block.
