A semiconductor device includes: a gate electrode formed above a semiconductor region; a drain region and a source region formed in portions of the semiconductor region located below sides of the gate electrode in a gate length direction, respectively; a plurality of drain contacts formed on the drain region to be spaced apart in a gate width direction of the gate electrode; and a plurality of source contacts formed on the source region to be spaced apart in the gate width direction of the gate electrode. The intervals between the drain contacts are greater than the intervals between the source contacts.
