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

Claim 0:
1. An integrated circuit device, comprising:
a first power rail;
a first active area extending in a first direction, the first active area including a first region defining a first threshold voltage (VT) and a second region defining a second VT different than the first VT, the first and second regions abutting one another to define a boundary therebetween;
a plurality of gates contacting the first active area and extending in a second direction perpendicular to the first direction;
a first transistor including the first region of the first active area and a first one of the gates, the first transistor having the first VT;
a second transistor including the second region of the first active area and a second one of the gates, the second transistor having the second VT; and
a tie-off transistor positioned at the boundary of the first region and the second region such that the first transistor is on a first side of the boundary in the first direction and the second transistor is on a second side of the boundary in the first direction, the tie-off transistor including the first active area and a third one of the gates, wherein the third gate is positioned directly over the boundary and is connected to the first power rail.
