Abstract:
A method of forming a semiconductor structure includes forming a multi-layer structure. The multi-layer structure has a substrate and two or more nanosheet layers formed above the substrate. The method also includes forming a bottom isolation layer between the substrate and the two or more nanosheet layers. The method further includes performing a fin reveal in the multi-layer structure after formation of the bottom isolation layer to form a fin. The two or more nanosheet layers provide a channel stack for a nanosheet field-effect transistor.

Claim (Index 2):
The method of  claim 1 , wherein forming the multi-layer structure comprises forming alternating layers of a first material and a second material, the multi-layer structure comprising:\n the substrate comprising the first material; an etch stop layer formed over the substrate, the etch stop layer comprising the second material; a sacrificial layer formed over the etch stop layer, the sacrificial layer comprising the first material; and the channel stack formed over the first sacrificial layer, the channel stack comprising the two or more nanosheet layers and two or more additional sacrificial layers, the two or more nanosheet layers comprising the first material and the two or more additional sacrificial layers comprising the second material.
