Patent ID: 11955517
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  B | IPC B  H

Claim 15:
16. A semiconductor device comprising:
a first channel active pattern protruding from a substrate and extending in a first direction;
a second channel active pattern protruding from the substrate and extending in the first direction, wherein the first and second channel active patterns are separated from one another in the first direction;
a field insulation layer disposed between the first channel active pattern and the second channel active pattern on the substrate;
a source/drain region disposed between the first channel active pattern and the field insulation layer and including an epitaxial layer;
a first gate pattern disposed on the first channel active pattern and including a first gate and a first gate spacer; and
a second gate pattern disposed on the field insulation layer and including a second gate and a second gate spacer,
wherein a first portion of the second gate pattern overlaps with a portion of the first channel active pattern,
wherein a second portion of the second gate pattern overlaps with the field insulation layer,
wherein a bottom of the second gate is higher than a lowermost part of the source/drain region, and
wherein a bottom of the field insulation layer is lower than the lowermost part of the source/drain region.
