内容記述
This paper describes method improvement performance of ion-implanted vertical bipolar junction transistor (BJT) on free-standing gallium nitride (GaN) substrates. This BJT consists of emitter region that is fabricated by Si-ion implantation. We achieved grounded emitter current amplification factor of 6. But, base region’s contact resistance was high and base contact became schottky contact.So, we research optimal conditions for ohmic contact of base electrode and found out best method of formation that is Ni electrode with 400 oC alloy.
