Abstract

See full text

A high electron mobility transistor (HEMT) includes a semiconductor channel layer, a semiconductor barrier layer, a patterned semiconductor capping layer, and a patterned semiconductor protection layer disposed on a substrate in sequence. The HEMT further includes an interlayer dielectric layer and a gate electrode. The interlayer dielectric layer covers the patterned semiconductor capping layer and the patterned semiconductor protection layer, and includes a gate contact hole. The gate electrode is disposed in the gate contact hole and electrically coupled to the patterned semiconductor capping layer, where the patterned semiconductor protection layer is disposed between the gate electrode and the patterned semiconductor capping layer. The resistivity of the patterned semiconductor protection layer is between the resistivity of the patterned semiconductor capping layer and the resistivity of the interlayer dielectric layer.
