摘要：
In a semiconductor diamond device, there is provided an ohmic electrode that is chemically, and thermally stable, and is excellent in respect of low contact resistance, and high heat resistance. A nickel-chromium alloy, or a nickel-chromium compound, containing Ni, and Cr such as Ni6Cr2 or Ni72Cr18Si10, which is chemically and thermally stable, is formed on a semiconductor diamond by a sputtering process and so forth, to thereby obtain the semiconductor diamond device provided with an excellent ohmic electrode. If heat treatment is applied after forming the nickel-chromium alloy, or the nickel-chromium compound, it is improved in characteristics.
