High density nanosheet diodes
Embodiments are directed to a method for forming a semiconductor structure by depositing a stack of alternating layers of two materials over a substrate and defining field-effect transistor (FET) and diode regions. The method further includes depositing a mask, where the mask covers only the FET region while leaving the diode region uncovered. The method further includes doping the material in the diode region with a dopant, implanting epitaxial material with another dopant to form PN junctions, stripping the mask from the structure, forming a metal gate conductor over the FET region, and depositing a metal over the substrate to create terminals.
