A circuit structure includes a first gate structure, a first gate structure, a first multi-connected channel layer, and a second transistor. The first gate structure has a first extension direction, and the first gate structures has opposite first end and second end. The first gate structure is all surrounded by the first multi-connected channel layer, and a plane direction of the multi-connected channel layer is perpendicular to the first extension direction. The first gate structure and the first multi-connected channel layer form a first transistor. The second transistor is disposed in the first multi-connected channel layer. A second gate structure or a channel of the second transistor is electrical connected to the first multi-connected channel layer. |
