Assignee: INTEL CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H  B | IPC B  H

Claim 0:
1. An integrated circuit structure, comprising:
a base;
a body over the base, the body comprising a semiconductor material, the body being in the form of a nanowire, nanoribbon or nanosheet and having a first end portion and a second end portion;
a gate structure wrapped around the body between the first end portion and the second end portion, the gate structure comprising a gate electrode and a gate dielectric between the gate electrode and the body;
a source region laterally adjacent to and in contact with the first end portion;
a drain region laterally adjacent to and in contact with the second end portion;
a first spacer material on opposite sides of the gate structure, the first spacer material above the first end portion of the body;
a second spacer material on opposite sides of the gate structure and under the first end portion and the second end portion of the body, the second spacer material having a composition; and
a dielectric material layer beneath the source region and beneath the drain region and in contact with a bottommost surface of the source region and the drain region, the dielectric material layer having a composition the same as the composition of the second spacer material, and the dielectric material discontinuous with the second spacer material.
