Patent number: 5039578Abstract: A new technique for forming non-rectifying electrical contacts to III-V semiconductor materials, without the use of dopants or of an alloying procedure, is disclosed. In accordance with this technique, an electrical contact is formed simply by depositing a region of material (onto the semiconductor material) having a composition which includes at least one metal element and at least one of three specific Group V elements, i.e., P, As, or Sb, and having a bulk electrical resistivity equal to or less than about 250 .mu..OMEGA.-cm. Alternatively, a contact is formed by depositing nickel, or a nickel-containing material essentially free of gold and silver, and having a composition which does not include any of the three Group V elements. The nickel, or nickel-containing material, is then reacted with the substrate to form a compound having a composition which includes nickel as well as one of the three Group V elements.Type: GrantFiled: February 20, 1990Date of Patent: August 13, 1991Assignee: AT&T Bell LaboratoriesInventors: Amiram Appelbaum, Murray Robbins
