Classification: CPC H  G | IPC H

Claim 14:
15. A semiconductor device with a shared gate structure, comprising:
an active area having a first active area portion extending in a first direction parallel to a top surface of a substrate, and a protrusion protruding from the first active area portion and extending in a second direction perpendicular to the first direction and parallel to the top surface of the substrate;
a separation area extending in the second direction from a first end to a second end and which divides the first active area portion into a first active portion on a first side of the separation area and a second active portion on a second, opposite side of the separation area, and which divides a first portion of the protrusion into a first protrusion part on the first side of the separation area and a second protrusion part on the second side of the separation area, wherein the first end of the separation area is on the active area and the second end of the separation area is on the first portion of the protrusion;
two 3D corner portions of the active area adjacent to the first end of the separation area; and
a gate arranged above the active area to cover a channel area of the active area while exposing the two 3D corner portions, wherein:
the separation area extends in the second direction beyond a first edge of the gate, and also extends beyond a second edge of the gate opposite the first edge in the second direction, part of the gate extends beyond the separation area and beyond the active area in the second direction, and
the two 3D corner portions are between a first portion of the gate and a second portion of the gate in the first direction.
