Abstract
A semiconductor structure includes: a substrate and a fin protruding from the substrate. The fin comprises a first semiconductive layer over the substrate, a second semiconductive layer over the first semiconductive layer, and a dielectric layer disposed between the first semiconductive layer and the second semiconductive layer and electrically isolated from the first semiconductive layer and the second semiconductive layer. The semiconductor structure further includes a gate electrode including: a first conductive portion extending along two opposite sidewalls of the first semiconductive layer and along an upper surface of the substrate; and a second conductive portion electrically isolated from the first conductive portion and extending along two opposite sidewalls of the second semiconductive layer and along an upper surface of the fin.
