    摘要: A method for manufacturing a semiconductor device includes forming a plurality of pillars by etching a semiconductor substrate, forming a gate dielectric layer on sidewalls of the pillars and on surfaces of the semiconductor substrate between the pillars, forming an implant damage in a portion of the gate dielectric layer between two pillars by implanting ions into the portion of the gate dielectric layer, forming vertical gates to cover the sidewalls of the pillars, and removing the implant damage.

    摘要: A nonvolatile memory device with a blocking layer controlling the transfer of electric charges in a charge storage layer includes the blocking layer having a first blocking layer in contact with the charge storage layer and a second blocking layer over the first blocking layer, wherein the first blocking layer has a greater energy band gap than the second blocking layer and the second blocking layer has a greater permittivity than the first blocking layer.
