Abstract
A high electron mobility transistor includes a channel layer; a barrier layer on the channel layer and having an energy bandgap greater than an energy bandgap of the channel layer; a gate structure on the barrier layer; a source electrode and a drain electrode spaced apart from each other on the barrier layer with the gate structure therebetween; a field plate electrically connected to the source electrode and extending above the gate structure; and a field dispersion layer in contact with the barrier layer and the drain electrode. The field dispersion layer may extend toward the gate structure.
