Abstract
A semiconductor device capable of easily setting the sheet resistance of a resistive element or the like to an arbitrary value is obtained. This semiconductor device comprises a first silicide film formed on a first silicon region and a second silicide film, formed on a second silicon region, consisting of the same silicide material as the first silicide film and differing from the first silicide film in film quality to have a sheet resistance value different from that of the first silicide film. When an impurity is introduced into the second silicide film itself so that the second silicide film differs from the first silicide film in film quality in this case, for example, a second silicide film having an arbitrary high sheet resistance value can be obtained by controlling the type of and an introduction condition for the impurity.
