A semiconductor structure is provided that includes a pFET device including a first functional gate structure containing at least a p-type work function metal and present on physically exposed surfaces, and between, each Si channel material nanosheet of a first set of vertically stacked and suspended Si channel material nanosheets. The structure further includes an nFET device stacked vertically above the pFET device. The nFET device includes a second functional gate structure containing at least an n-type work function metal present on physically exposed surfaces, and between, each Si channel material nanosheet of a second set of vertically stacked and suspended Si channel material nanosheets. |
