Abstract
Embodiments are disclosed for a semiconductor structure. The semiconductor structure includes a first nanosheet layer. The first nanosheet layer includes a first channel region, and a heavily doped epitaxial region of a first type. Further, the semiconductor structure includes a second nanosheet layer. The second nanosheet layer includes a second channel region, a heavily doped epitaxial region of a second type disposed above the first nanosheet layer, and a first gate surrounding the first channel region and the second channel region. Additionally, the semiconductor structure includes a protection diode. The protection diode includes a source, a drain, and a second gate. The drain is connected to the first gate, and the second gate is connected to the source.
