Abstract:
An enhancement-mode field-effect transistor comprising at least: a heterojunction formed by at least one first layer comprising GaN and at least one second layer comprising AlGaN; and a gate comprising P-doped diamond, such that a first part of the second layer of the heterojunction defining a channel of the transistor is arranged between the gate and the first layer of the heterojunction; and in which the first part of the second layer of the heterojunction has a thickness of between approximately 5 nm and 12 nm and an aluminium content of between approximately 15% and 20%.

Claim (Index 11):
The method according to  claim 10 , further comprising, between the creating of the heterojunction and the creating of the gate:\n depositing at least one first passivation dielectric layer onto the second layer of the heterojunction; creating at least two first openings through the first passivation dielectric layer; creating at least two electric contacts at least in the two first openings and electrically connected to the source and to the drain of the transistor via the second layer of the heterojunction; depositing at least one second passivation dielectric layer onto the two electric contacts and onto the first passivation dielectric layer; and creating at least one second opening passing through the first and second passivation dielectric layers and forming an access to the first portion of the second layer of the heterojunction; and wherein the gate is made at least by carrying out the following: creating at least one layer of p-doped diamond in the second opening, on the first portion of the second layer of the heterojunction and on the second passivation dielectric layer; and etching of the p-doped diamond layer with stoppage on the second passivation dielectric layer, such that a remaining portion of the layer of p-doped diamond forms the gate.
