| 摘要 |
This patent relates to a semiconductor memory device and a method of fabricating the same. The semiconductor memory device may include a semiconductor substrate in which a tunnel insulating layer, and a first conductive layer. At least a portion of the semiconductor substrate is removed to form a trench. A first insulating layer may be formed on an internal surface of the trench. A shield layer may be made of a conductive material is formed on the first insulating layer. A second insulating layer may be formed on the shield layer and is configured to gap fill the trench.
