Description

An optimal annealing process was developed for sintering Au-Ge ohmic contacts to ion-implanted semi-insulating InP substrates. Contacts were annealed using a standard furnace, graphite strip heater and a lamp annealer. Alloying at 3750C for 3 min was found to be most suitable for achieving good contact morphology and lowest contact resistivity. Of the three techniques, the lamp annealing technique was found to give the best results when contacts were annealed under a Si02 cap. Contact resistivity as low as 8 x 10-6 cm2 was obtained for ion-implanted n+ layers in semi-insulating InP. (author)
