Patent ID: 11862634
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  B | IPC H

Claim 13:
14. A semiconductor structure, comprising:
first silicon-containing layers and second silicon-containing layers extending lengthwise in a first direction over a substrate;
a first gate structure extending lengthwise in a second direction different from the first direction and wrapping around the first silicon-containing layers and the second silicon-containing layers;
third silicon-containing layers and fourth silicon-containing layers extending lengthwise in the first direction over the substrate, wherein the first silicon-containing layers are narrower than the third silicon-containing layers in the second direction; and
a second gate structure extending lengthwise in the second direction and wrapping around the third silicon-containing layers and the fourth silicon-containing layers,
wherein a first distance between the first silicon-containing layers and the second silicon-containing layers in the second direction is smaller than a second distance between the third silicon-containing layers and the fourth silicon-containing layers in the second direction.
