Abstract
A semiconductor device structure includes a substrate, a channel layer, a barrier layer and a doped group III-V layer. The channel layer is disposed on the substrate. The barrier layer is disposed on the channel layer. The doped group III-V layer is disposed on the barrier layer. The doped group III-V layer includes a first portion and a second portion. The first portion has a first concentration of a first element. The second portion is adjacent to the first portion and has a second concentration of the first element. The gate structure is disposed on the first portion of the doped group III-V layer. The first concentration of the first element is different from the second concentration of the first element.
