    摘要: A multi-gate transistor includes a semiconductor fin over a substrate. The semiconductor fin includes a central fin formed of a first semiconductor material; and a semiconductor layer having a first portion and a second portion on opposite sidewalls of the central fin. The semiconductor layer includes a second semiconductor material different from the first semiconductor material. The multi-gate transistor further includes a gate electrode wrapping around sidewalls of the semiconductor fin; and a source region and a drain region on opposite ends of the semiconductor fin. Each of the central fin and the semiconductor layer extends from the source region to the drain region.
