Parts of the first silicon nitride layer are etched out by a photo-lithography defined pattern process. The silicon substrate is then implanted by nitrogen ion and a second silicon nitride layer formed on the first silicon nitride layer is retro-etched to make a gap on the side wall of the first silicon nitride layer. By using the gap wall as a mask, the part of silicon nitride layer without covered by the mask and the part of silicon substrate with doped ion of nitrogen are then removed. A field oxide layer is formed on the part of silicon substrate without covered by the first silicon nitride layer. The region that the bird beak conventionally formed is then not oxidized so the bird beak phenomenon is improved.
