Patent abstract
A nonvolatile memory device and a method for fabricating the same is disclosed, to prevent a “smiling” phenomenon in an ONO layer, thereby improving the programming and erasing characteristics, reliability and yield. The device generally includes a semiconductor substrate; a gate insulating layer, a selection gate and a first insulating layer on the semiconductor substrate; an ONO layer formed on the semiconductor substrate including the selection gate; and a control gate formed on the ONO layer at least partially overlapping with the selection gate.
