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 14):
A nanosheet device, comprising:\n a substrate, having a first device region and a second device region; a plurality of second material layers at the first device region, stacked with a plurality of first inner spacers at a first edge region, wherein a first one of the first inner spacers is disposed on the substrate; a plurality of first material layers at the second device region, stacked with a plurality of second inner spacers at a second edge region, wherein a first one of the first material layers is disposed on the substrate, wherein the first material layers in material are different from the second material layers; a pair of first spacers disposed on a top layer of the second material layers at the first edge region; a pair of second spacers disposed on a top layer of the first material layers at the second edge region; a first insulating layer, disposed on the top layer of the second material layers between the pair of the first spacers; a second insulating layer, disposed on the top layer of the first material layers between the pair of the second spacers; a first metal layer, filled between the first spacers and the first inner spacers at the first device region; a second metal layer, filled between the second spacers and the second inner spacers at the second device region; a pair of first electrode layers, disposed on the substrate at both outer sides of the first inner spacers; and a pair of second electrode layers, disposed on the substrate at both outer sides of the second inner spacers.
