Abstract

A MOSFET in which the gate electrode is formed of a polycrystalline silicon film, a silicon nitride film having a nitrogen surface density of lens than 8.times.10.sup.14 cm.sup.-2, and a tungsten film--these films formed one upon another in the order mentioned. The gate electrode thus formed, serves to shorten the delay time of the MOSFET.
