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

Claim 5:
6. 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 further beneath the source region and beneath the drain region and in contact with a bottommost surface of the source region and the drain region, wherein a portion of the second spacer material beneath the source region is discontinuous with a portion of the second spacer material on opposite sides of the gate structure and under the first end portion and the second end portion of the body, and wherein a portion of the second spacer material beneath the drain region is discontinuous with a portion of the second spacer material on opposite sides of the gate structure and under the first end portion and the second end portion of the body.
