The photoresist layer pattern is removed. A gap-fill oxide layer is formed on the substrate. The first CMP process is performed on a predetermined thickness of the gap-fill oxide layer and the second silicon nitride layer. The remaining second silicon nitride layer is etched to expose the second pad oxide layer. The second CMP process is performed on the gap-fill oxide layer and the second pad oxide layer to expose the first silicon nitride layer. The first silicon nitride layer is etched to form the isolation layer(20).
