ABSTRACT:
A 10.sup.-6 ohm cm.sup.2 ohmic contact is provided by formation of a 20-50 Angstroms deep surface region with a net donor density of higher than 5.times.10.sup.19 /cc. An amphoteric dopant of Si or Ge is incorporated in a pinned Fermi level condition so that an enhanced surface donor concentration occurs.
