A semiconductor device includes a substrate material with a semiconductor material with a predetermined crystal orientation, a gate stack having a plurality of nanosheet channel layers, each nanosheet channel layer being controlled by metal gate layers located above and below the nanosheet channel layer, each nanosheet channel layer having the same semiconductor material and crystal orientation as that of the substrate, and a source/drain region on opposite sides of the gate stack. Each source/drain region includes bridging structures respectively connected to each nanosheet channel layer.
