Abstract: PURPOSE: A method for manufacturing a gate electrode of a semiconductor device is to minimize a thermal damage to a titanium silicide layer by performing a reoxidization process in a shorter interval of time than that of a conventional thermal oxidation process, and to provide a uniform reoxidization layer by using a wet method. CONSTITUTION: A gate oxidation layer(12), a polysilicon layer and a titanium silicide layer are sequentially stacked on a semiconductor substrate(11). A mask oxidation layer(16) is evaporated on the titanium silicide layer. The mask oxidation layer, titanium silicide layer, polysilicon layer and gate oxidation layer are patterned to form a gate electrode. A resultant substrate in which the gate electrode is formed is reoxidized. The reoxidization process is performed at a predetermined temperature in a wet rapid thermal oxidation method.

Abstract: PURPOSE: A method for manufacturing a shallow trench for isolating a semiconductor device is provided to improve an isolation characteristic in an edge portion of the trench by forming a nitride layer in the edge portion of the trench, and to effectively prevent a trench edge defect by having the nitride layer remaining in the edge portion of the trench function as an etch stop layer even when a misalignment occurs in a subsequent etching process for a contact hole. CONSTITUTION: A pad oxidation layer(12) and the first nitride layer are formed on a silicon wafer(11), and are patterned by a mask having a trench pattern to form a moat pattern. A predetermined depth of the silicon wafer is etched to form a trench. The silicon wafer is thermally oxidized to grow a liner oxidation layer(13) on an inner wall of the trench. A thick oxidation layer is evaporated on the entire surface of the silicon wafer to fill the trench, and the oxidation layer is planarized by using the nitride layer as a buffer layer. After the first nitride layer remaining on the silicon wafer is eliminated, the second nitride layer is evaporated on the entire surface of the silicon wafer. The second nitride layer is patterned to have the second nitride layer remain on the silicon wafer of a predetermined width on the oxidation layer and trench.
