Abstract
A semiconductor device includes a semiconductor substrate, a first semiconductor channel layer, a second semiconductor channel layer, and an isolation structure. The first semiconductor channel layer, the second semiconductor channel layer, and the isolation structure are disposed above the semiconductor substrate. The isolation structure includes a vertical portion, a first horizontal portion, and a second horizontal portion. The vertical portion is disposed between the first semiconductor channel layer and the second semiconductor channel layer in a horizontal direction. The first horizontal portion is disposed between the first semiconductor channel layer and the semiconductor substrate in a vertical direction. The second horizontal portion is disposed between the second semiconductor channel layer and the semiconductor substrate in the vertical direction. The first horizontal portion and the second horizontal portion are connected with the vertical portion.
