Abstract:
A method for fabrication a nanosheet device includes providing forming a stacked layer on a substrate, having first material layers and second material layers in different materials, alternatingly stacked up. The stacked layer is patterned to a stacked fin. A dummy stack is formed on the stacked fin. An etching back process is performed with the dummy stack with spacers to etch the stacked fin and expose the substrate. Laterally etches the first material layers and the second material layers, to have indent portions. Inner spacers fill the indent portions. A first/second source/drain layer is formed on the substrate at both sides of the dummy stack. Etching process is performed to remove the dummy gate of the dummy stack and the selected one of the first material layers and the second material layers between the inner spacers. Metal layer fills between the spacers and the inner spacers.

Claim (Index 20):
The nanosheet device of  claim 14 , wherein a number of the first material layers at the first device region is less by one than a number of the second material layers at the second device region.
