Abstract

A high-electron-mobility field-effect transistor includes a superposition of first and second layers of semiconductor materials so as to form an electron gas layer and includes a gate stack arranged on the superposition. The gate stack includes a conductive electrode and an element made of p-doped semiconductor material, arranged between the conductive electrode and the superposition. The gate stack includes a first dielectric layer arranged between the conductive electrode and the element made of semiconductor material. The element made of semiconductor material, the first dielectric layer, and the conductive electrode have aligned lateral flanks.
