IPC: H01L21/76
Filed: 1999-05-27
Abstract: PURPOSE: A method for manufacturing a shallow trench for isolating a semiconductor device is provided to prevent a characteristic curve of a gate voltage and a drain current from changing, by basically preventing a corner defect of a trench formed in an interface between an active region and an isolation region. CONSTITUTION: A pad oxidation layer(12) is grown by thermally oxidizing a silicon wafer(11). A nitride layer(13) is evaporated on the pad oxidation layer, and is patterned to form a nitride layer pattern wider than a trench width. A moat pattern(15) of a desired trench width is formed, masking the nitride layer pattern and a part of the exposed pad oxidation layer. A predetermined depth of the exposed pad oxidation layer and silicon wafer is etched using the moat pattern as a mask to form a trench in an isolation region of a semiconductor device. The moat pattern is eliminated, and a thick insulating layer is evaporated on the silicon wafer to fill the trench. A chemical mechanical polishing(CMP) process is performed regarding the nitride layer for planarization by using the nitride layer pattern as a buffer layer. The silicon wafer is wet-cleaned to eliminate the nitride layer pattern.
