Abstract:
A substrate structure having a set of nanosheet layers and a set of sacrificial layers stacked upon a substrate is received and a dummy gate is formed upon the nanosheet layers and the sacrificial layers. A portion of a subset of the set of sacrificial layers and a subset of the set of nanosheet layers is etched. A portion of a subset of the subset of sacrificial layers is etched to create divots within the sacrificial layers. A divot fill layer is deposited. The divot fill layer is etched to form an inner spacer between the nanosheet layers. A source/drain region is formed adjacent to the nanosheet layers and the divots. A remaining portion of the subset of the sacrificial layers is removed. The subset of the nanosheet layers is etched to a desired channel thickness producing faceted surfaces between the subset of nanosheet layers and the inner spacer.

Claim (Index 6):
The computer usable program product of  claim 4 , wherein the subset of the set of sacrificial layers and the subset of the set of nanosheet layers are etched to be substantially aligned to one or more sides of the hard mask.
