Nanosheet gated diode

Abstract:

One or more gated nanosheet diodes are disposed on a substrate and made from a nanosheet structure. A first (second) source/drain (S/D) is disposed on the substrate. The first (second) S/D has a first (second) S/D doping concentration with a first (second) S/D doping type. One or more p-n junctions form one or more respective diodes. There is a first side and a second side of each of the p-n junctions. The first (second) sides of the p-n junctions electrically and physically connect to the first (second) S/Ds and have the same type of doping, respectively. A gate stack, made of a gate dielectric layer and a gate metal, interfaces and surrounds each of the p-n junctions.
