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

Claim 0:
1. A semiconductor device comprising:
a substrate having an active region defined by a device isolation film, the active region providing a first channel region;
a first source/drain region in the active region on first and second sides of the first channel region;
a gate structure having a first gate insulating film, a shared gate electrode, and a second gate insulating film sequentially arranged on the active region, the shared gate electrode having an extended portion on the device isolation film;
a cover semiconductor layer on the second gate insulating film and electrically separated from the active region to provide a second channel region;
a second source/drain region in the cover 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.
