CONSTITUTION: An epi-silicon wafer(11) is formed by a silicon monocrystal growth, which has a shallow buried layer(12) as deep as a bottom of a trench. A moat pattern for forming the trench is formed on the epi-silicon wafer. The trench is formed by plasma dry-etching the exposed epi-silicon wafer by using the buried layer as an etch stop layer while using the moat pattern as a mask. A thick insulating layer is evaporated on the entire surface of the epi-silicon wafer to fill the trench, and the insulating layer is planarized.
