    Abstract: Implementations described herein provide a method of forming a semiconductor device. The method includes forming a nanostructure having a first set of layers of a first material and a second set of layers, alternating with the first set of layers, having a second material. The method further includes depositing a hard mask on a top layer of the first set of layers, the hard mask including a first hard mask layer on the top layer of the first set of layers and a second hard mask layer on the first hard mask layer. The method also includes depositing elements of a cladding structure on sidewalls of the nanostructure and the hard mask. The method further includes removing a top portion of the cladding structure. The method further includes removing the second hard mask layer after removing the top portion of the cladding structure.

    Abstract: A semiconductor device includes a substrate, a first insulating structure, a second insulating structure, at least one first active semiconductor fin, and at least one second active semiconductor fin. The first insulating structure and the second insulating structure are disposed on the substrate. The first active semiconductor fin is disposed on the substrate and has a protruding portion protruding from the first insulating structure. The second active semiconductor fin is disposed on the substrate and has a protruding portion protruding from the second insulating structure. The protruding portion of the first active semiconductor fin and the protruding portion of the second active semiconductor fin have different heights.
