Abstract :
Ohmic contacts have been fabricated to n-type GaAs with an alloy of AL-Ge which has an eutectic temperature of 424°C with 53- weight percent Germanium. The lowest contact resistance of 1.4 × 10-6Ω.cm2was measured with a transfer length transmission line structure. The application to GaAs integrated-circuit design is demonstrated.
