Abstract: PURPOSE:To prevent a reaction of a wiring part with Si of a substrate and to obtain a semiconductor device equipped with an electrode wiring part which does not increase a contact resistance value by a method wherein the electrode wiring part composed of Al12Mo is used. CONSTITUTION:An SiO2 2 having a contact hole is formed on a p-type Si substrate 1; an n-type layer 3 is formed on the surface of the Si substrate 1 of the contact hole. In succession, an electrode wiring part 4 composed of Al12Mo is formed; when an Al12Mo film is to be deposited, the substrate is heated in accordance with a deposition method and a deposition speed so as to promote formation of a single-crystal Al12Mo layer 5, and thermal stability of the electrode is enhanced further. A p-n junction using the electrode of this structure does not change its characteristic by an alloy at 450 deg.C and does not increase a contact resistance value of the electrode although a thickness of the n-type layer is shallow to be 0.1mum. This is because a solid solution reaction of Al12Mo with Si is not caused at least up to 500 deg.C.
