    摘要: A method of fabricating a non-volatile memory device having a charge trapping layer includes forming a tunneling layer, a charge trapping layer, a blocking layer and a control gate electrode layer over a substrate, forming a mask layer pattern on the control gate electrode layer, performing an etching process using the mask layer pattern as an etching mask to remove an exposed portion of the control gate electrode layer, wherein the etching process is performed as excessive etching to remove the charge trapping layer by a specified thickness, forming an insulating layer for blocking charges from moving on the control gate electrode layer and the mask layer pattern, performing anisotropic etching on the insulating layer to form an insulating layer pattern on a sidewall of the control gate electrode layer and a partial upper sidewall of the blocking layer, and performing an etching process on the blocking layer exposed by the anisotropic etching, wherein the etching process is performed as excessive etching to remove the charge trapping layer by a specified thickness.

    摘要: Disclosed herein is a nonvolatile memory device having a charge trapping layer and a method of making the same. The nonvolatile memory device includes a substrate, a tunneling layer disposed on the substrate, a charge trapping layer disposed on the tunneling layer, a first blocking layer disposed on the charge trapping layer, a second blocking layer disposed on the first blocking layer, and a control gate electrode disposed on the second blocking layer. A first band gap between the first blocking layer and the charge trapping layer is larger than a second band gap between the second blocking layer and the charge trapping layer.
