Provided is a semiconductor structure with shared gated devices. The semiconductor structure comprises a substrate and a bottom dielectric isolation (BDI) layer on top of the substrate. The structure further comprises a pFET region that includes a p-doped Source-Drain epitaxy material and a first nanowire matrix above the BDI layer. The structure further comprises an nFET region that includes a n-doped Source-Drain epitaxy material and a second nanowire matrix above the BDI layer. The structure further comprises a conductive gate material on top of a portion of the first nanowire matrix and the second nanowire matrix. The structure further comprises a vertical dielectric pillar separating the pFET region and the nFET region. The vertical dielectric pillar extends downward through the BDI layer into the substrate. The vertical dielectric pillar further extends upward through the conductive gate material to a dielectric located above the gate region.
