Abstract:
A method of manufacturing a semiconductor device, comprising the steps of:forming a semiconductor film consisting essentially of a semiconductor containing a semiconductor element on a substrate;depositing a first conductive film containing a metal and nitrogen on said semiconductor film, said metal being of such a type that a decrease in Gibbs free energy occurring in forming a nitride of said metal from said metal is smaller than a decrease in Gibbs free energy occurring in forming a nitride of said semiconductor element from said semiconductor element; andheating said first conductive film, thereby changing all or part of said first conductive film to a second conductive film consisting essentially of said metal, and thereby forming a third conductive film containing nitrogen and said semiconductor element and positioned in contact with said semiconductor film between said second conductive film and said semiconductor film to form at least one of an electrode and a wiring which includes said semiconductor film, said second conductive film, and said third conductive film.
