Abstract: PURPOSE: To obtain a Schottky barrier diode in which a barrier height is adjusted accurately and in which a forward characteristic and a backward characteristic can be adjusted, by installing a barrier metal which displays different barrier heights with reference to a semiconductor and which is composed of an alloy of two or more kinds of metal materials combined so as not to form a metal compound. CONSTITUTION: When a Ti-Y alloy by two kinds of metal as a metal Ti and a metal Y is, e.g. a eutectic alloy, its texture shows a texture in which the metal Ti and the metal Y are mixed very fine. Consequently, this Schottky barrier diode SBD which has a barrier metal composed of the Ti-Y alloy has the intermediate barrier height φb as the barrier height φb of an SBD in which respective metals are single metal. When the composition of the alloy is adjusted, the SBD having the barrier height φb which cannot be achieved by a single metal can be obtained, and the electric characteristic of the SBD can be controlled accurately. Consequently, it is possible to obtain the SBD having a forward characteristic and a backward characteristic which cannot be obtained in the SBD which uses a single metal as a barrier metal.
