Zusammenfassung: | A semiconductor structure is presented including semiconductor layers of a first nanosheet stack, semiconductor layers of a second nanosheet stack formed over and having a stepped nanosheet formation with respect to the semiconductor layers of the first nanosheet stack, a first epitaxial growth formed adjacent the semiconductor layers of the first nanosheet stack, and a second epitaxial growth formed adjacent the semiconductor layers of the second nanosheet stack such that the second epitaxial growth has a stepped formation with respect to the first epitaxial growth. The second epitaxial growth has a volume greater than a volume of the first epitaxial growth. |
