Abstract
A semiconductor device structure is provided. The semiconductor device structure includes multiple first semiconductor nanostructures over a first semiconductor fin and multiple second semiconductor nanostructures over a second semiconductor fin. A topmost second semiconductor nanostructure of the second semiconductor nanostructures is thinner than one or more of lower semiconductor nanostructures of the second semiconductor nanostructures. The semiconductor device structure also includes a first metal gate stack wrapped around the first semiconductor nanostructures. The semiconductor device structure further includes a second metal gate stack wrapped around the second semiconductor nano structures.
