Classification: CPC H | IPC H

Claim 13:
14. An integrated circuit, comprising:
a fin field effect transistor (finFET) over a semiconductor substrate, the finFET including:
a plurality of fins including a first fin and a second fin, the first fin having a first source region and a first body region abutting the first source region, the second fin having a second source region and a second body region abutting the second source region, the first and second source regions having a first conductivity type and the first and second body regions having a second conductivity type, opposite from the first conductivity type;
a drain region including drain contact region;
a first drain drift region extending from the first body region toward the drain contact region and a second drain drift region extending from the second body region toward the drain contact region, the drain drift regions having the first conductivity type;
a merged drain region between the first and second drain drift regions and the drain contact region, the merged drain region including a curved portion that connects to the first and second drain drift regions.
