Electrical properties for Si-implanted n-type GaN and AlGaN layers and contact resistances of ohmic contacts (Ti/Al) formed on these layers were examined. Experimental results clearly show that ohmic contacts on n-type GaN and n-type AlGaN with a low specific-contact resistance of under 10−7 and 10−6 Ω cm2 can be fabricated on the high concentration n-type layers, which have been formed by Si ion implantation (30 keV: 1 × 1014, 5 × 1014, 1 × 1015 and 2 × 1015/cm2) and subsequent annealing at 1250 °C for 2 min using a Si3N4 as a surface protection layer. |
