Abstract
A semiconductor device includes: an underlying substrate; a semiconductor layer formed on the underlying substrate; electrode patterns in which a drain electrode and a source electrode are alternately arranged along an array direction determined in advance, on the semiconductor layer; and a group of gate fingers each having a shape extending in an extending direction which is different from the array direction. Each of the gate fingers is disposed in a region between the drain electrode and the source electrode. Moreover, the gate fingers are arranged at positions displaced from one another in the extending direction.
