Abstract

Embodiments herein include semiconductor structures that may include a semiconductor structure for improving the switching speed of a first transistor. The first transistor may include a first source/drain (S/D), a metal gate, a spacer between the first S/D and the metal gate, and a first nanosheet channel. The first nanosheet channel may include: a gate section with silicon-germanium (SiGe) surrounded by the metal gate; and a junction section comprising silicon surrounded by the spacer.
