Hydrogen Ion Bombardment of GaAs for Device Isolation

  • I. J. Saunders

Multiple energy bombardments of n+ GaAs with the three hydrogen isotopes have shown that deuterons offer great advantages for device isolation. Carrier removal is accomplished at a deuteron dose only 5% of that needed with protons, significantly reducing processing time. Higher doses may be needed for thermal stability, but in all cases deuteron bombardment has been found to be more stable for a given dose. A model for the carrier removal is described.
