Patent ID: 11908864
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A semiconductor device comprising:
a semiconductor substrate;
a first first-conductive type fin structure protruding from the semiconductor substrate;
a second first-conductive type fin structure protruding from the semiconductor substrate;
a first gate structure covering first channel regions of the first and second first-conductive type fin structures, the first channel regions being above an isolation insulating layer;
a first second-conductive type fin structure protruding from the semiconductor substrate;
a second second-conductive type fin structure protruding from the semiconductor substrate;
a second gate structure covering second channel regions of the first and second second-conductive type fin structures, the second channel regions being above the isolation insulating layer; and
a carbon barrier region disposed at a region of the semiconductor substrate between the second first-conductive type fin structure and the first second-conductive type fin structure
wherein the carbon barrier region extends to a bottom of each of the second first-conductive type fin structure and the first second-conductive type fin structure.
