Semiconductor Device

Abstract

The invention relates to a semiconductor component comprising at least one field effect transistor, said transistor comprising at least a back barrier layer, a buried layer arranged on the back barrier layer, a channel layer arranged on the buried layer, a barrier layer arranged on the channel layer, and a gate layer arranged on the barrier layer, wherein the barrier layer comprises AlzGa1-zN and wherein the buried layer comprises AlxGa1-xN and at least one dopant causing a p-type conductivity, and wherein the gate layer comprises any of GaN and/or AluInvGa1-v-uN. A field effect transistor according to the disclosure may be configured to show a gate threshold voltage which is higher than approximately 0.5 V or higher than approximately 1.0 V.
