Abstract
AuBe ohmic contacts to p-In0.53Ga0.35Al0.12As (Be:5*1018 cm-3) formed by rapid thermal annealing (RTA) have been studied and compared with those formed by conventional alloying. Using thermally evaporated AuBe, specific contact resistances in the low mu Omega .cm2 range have been achieved by both methods. However, contacts made by RTA demonstrated good thermal stability whereas the contacts by conventional alloying degraded more than one order of magnitude at 250 degrees C for 100 h.
