摘要:
Provided is a method for fabricating a nonvolatile memory device capable of improving charge retention characteristics. The method for fabricating a nonvolatile memory device includes forming a charge trapping layer with a memory region and a charge blocking region on a semiconductor substrate, and trapping charges in the charge blocking region of the charge trapping layer.
