    • A nonvolatile memory device and method for fabricating the same are provided. The method for fabricating the nonvolatile memory device comprises providing a substrate. A tunnel insulating layer and a first conductive layer are formed in the substrate. A trench is formed through the first conductive layer and the tunnel insulating layer, wherein a portion of the substrate is exposed from the trench. A first insulating layer is formed in the trench. A second insulating layer is formed on sidewalls of the first insulating layer. A third insulating layer is conformably formed in the trench, covering the first insulating layer on a bottom portion of the trench and the second insulating layer on the sidewalls of the trench, wherein thickness of the third insulating layer on the sidewalls is thinner than that on the bottom of the trench. A control gate is formed on the third insulating layer in the trench.
    • 提供一种非易失性存储器件及其制造方法。 非易失性存储器件的制造方法包括提供衬底。 在衬底中形成隧道绝缘层和第一导电层。 通过第一导电层和隧道绝缘层形成沟槽,其中衬底的一部分从沟槽露出。 在沟槽中形成第一绝缘层。 第二绝缘层形成在第一绝缘层的侧壁上。 第三绝缘层顺应地形成在沟槽中,覆盖沟槽底部的第一绝缘层和沟槽侧壁上的第二绝缘层,其中侧壁上的第三绝缘层的厚度比在 沟渠的底部。 控制栅极形成在沟槽中的第三绝缘层上。
