    • A method for forming a semiconductor device is provided to avoid attack in a CMP process for a gate polysilicon layer by performing a dishing process on a part of the center of an isolating oxide layer during a CMP process for the isolating oxide layer so that an overlay vernier having a step is formed. A predetermined depth of a semiconductor substrate(100) is etched to form a trench by using a first exposure mask. The trench is filled with an isolating oxide layer(110). A CMP process is performed to form a step wherein a predetermined thickness of the isolation oxide layer can be left in the trench. A hard mask layer is formed on the resultant structure. The hard mask layer and the center of the isolating oxide layer are etched by a predetermined depth to form a main scale of an overlay vernier by using a second exposure mask. The hard mask layer is removed. After a gate polysilicon layer is formed on the resultant structure, a CMP process is performed.
