Full nanosheet airgap spacer
Abstract:
Embodiments disclosed herein include a nanosheet transistor for reducing parasitic capacitance. The nanosheet transistor may include a spacer region between a high-k metal gate and an epitaxial layer. The spacer region may include a first nanosheet stack with a first nanosheet and a second nanosheet. The spacer region may include an inner spacer region between the first nanosheet and the second nanosheet, and a side subway region located along an edge of the first nanosheet, the inner spacer region, and the second nanosheet.
