Radiation Annealing of GaAs Implanted with Si

Abstract
The use of radiation from halogen lamps to anneal implanted GaAs has been studied. Semi-insulating GaAs wafers implanted with 3×1012 cm-2 silicon at 70 keV were completely activated by 5 seconds rediation with or without encapsulation. The wafer temperature reached 950°C. This annealing method minimizes the thermal conversion of semi-insulating GaAs wafers.
