Abstract
A semiconductor device includes a first fin structure extending from a semiconductor substrate. A second fin structure is disposed over the first fin structure. The second fin structure includes a first layer including a first semiconductor material. The second fin structure further includes a second layer including a second semiconductor material disposed over the first layer. The second layer has a vertical sidewall. The second semiconductor material is different from the first semiconductor material. A gate structure is disposed over the semiconductor substrate and wraps around the first and second layers of the second fin structure.
