Assignee: TEXAS INSTRUMENTS INCORPORATED
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device, comprising:
a substrate; and
a fin field effect transistor (finFET) at a surface of the substrate, the finFET including:
fins of a semiconductor material;
a source in each of the fins, the source having a first conductivity type;
a body in each of the fins abutting the source, the body having a second conductivity type, opposite from the first conductivity type;
an extended drain region in each of the fins, the extended drain region abutting the body, opposite from the source, the extended drain region having the first conductivity type, wherein the extended drain region includes a center portion extending from the body, and first and second merge portions that extend from opposite sides of the center portion;
a first region in each merge portion, the first region having second conductivity type dopants;
a drain contact region to the extended drain region, opposite from the body, the drain contact region having the first conductivity type;
a gate dielectric layer on the body; and
a gate over the gate dielectric layer.
