Abstract

A high electron mobility transistor includes a substrate, a semiconductor channel layer, a semiconductor barrier layer, a gate field plate, a source electrode, at least one first field plate, and a second field plate. The gate field plate is disposed on the semiconductor barrier layer. The source electrode is disposed on one side of the gate field plate, and the first field plate is disposed on the other side of the gate field plate and laterally spaced apart from the gate field plate. The second field plate covers the gate field plate and the first field plate and is electrically connected to the source electrode, where the area of the second field plate is larger than the sum of the area of the gate field plate and the area of the first field plate when perceived from a top-down perspective.
