Patent ID: 11916078
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. A semiconductor device comprising:
a first semiconductor layer having a first channel region;
a first source/drain region in the first semiconductor layer on first and second sides of the first channel region;
a gate structure including a first gate insulating film, a shared gate electrode, and a second gate insulating film sequentially arranged on the first channel region, the shared gate electrode having an extended portion in a region that is free from overlap by a cover semiconductor layer in a direction that is perpendicular to an upper surface of the first semiconductor layer;
a second semiconductor layer on the second gate insulating film and electrically separated from the first semiconductor layer to provide a second channel region;
a second source/drain region in the second semiconductor layer on first and second sides of the second channel region;
first and second source/drain contacts respectively connected to the first and second source/drain regions; and
a shared gate contact connected to the extended portion of the shared gate electrode.
