Effects of oxygen plasma treatment on the formation of ohmic contacts to GaN and AlGaN
- Abstract:
-
The effects of oxygen plasma treatment prior to metal contact deposition have been studied for both n-and p-GaN, as well as n-AlGaN. In n-GaN, the as-deposited Ti/Al contacts change from rectifying to ohmic, and further improvements are observed after rapid thermal annealing (RTA). A specific contact resistivity better than 10-7 ω cm2 was obtained using a plasma treatment of 20 s at 30 W and 0.2 mbar, followed by RTA at 500°C in argon. The I-V characteristics of the Ti/Al contacts degraded wh...
