摘要:
A group III-N lateral Schottky diode is disclosed comprising a substrate (2), a nucleation layer (3) formed on the substrate (2), a buffer layer (4) formed on the nucleation layer (3), a group III-N channel stack (5) formed on the buffer layer (4), formed on the channel stack (5) a group III-N barrier (6) containing Aluminium whereby the Aluminium content of the barrier (6) decreases towards the channel stack (5), a passivation layer (8) formed on the group III-N barrier (6), a cathode (11) formed in an opening (9) through the passivation layer (8) whereby the opening (9) at least extends to the barrier (6), and; an anode (13) formed in another opening (10) through the passivation layer (8) thereby partially extending into the barrier (6), the anode forming a Schottky contact with the barrier (6).
