Description:
This study shows that an Al-Ti bilayer with an Al to Ti atomic ratio suitable for ohmic contacts on p-type 4H-SiC can be covered by a Ni film during the high temperature alloying process, without altering the ohmic nature, while eliminating a detrimental contact morphology caused by the presence of molten Al-Si during alloying. On 1× 10 20 cm− 3 Al-implanted 4H-SiC layer, the RT specific contact resistance of this Ni-Al-Ti contact measured by TLM-C method is (3±1)× 10− 6 Ωcm 2.
