摘要： A method of forming a shadow layer on a wafer bevel region is provided. First, a substrate having the wafer bevel region and a central region is provided. Thereafter, an upper insulator and a lower insulator are provided. The upper insulator is disposed on an upper surface of the substrate and at least covers the central region. The lower insulator is disposed on a lower surface of the substrate and at least covers the central region. A shadow layer is then formed on the upper surface which is not covered by the upper insulator and on the lower surface which is not covered by the lower insulator. Next, the upper insulator and the lower insulator are removed.

摘要： 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.
