Patent attributes
A method of manufacturing a nonvolatile memory device is provided. The method includes forming an isolation layer in a semiconductor substrate defining an active region and forming a molding pattern on the isolation layer. A first conductive layer is formed on a sidewall and a top surface of the molding pattern and on the semiconductor substrate. The first conductive layer on the top surface of the molding pattern is selectively removed forming a conductive pattern. The conductive pattern includes a body plate disposed on the active region and a protrusion which extends from an edge of the body plate onto the sidewall of the molding pattern. The molding pattern is then removed. An inter-gate dielectric layer is formed on the isolation layer and the conductive pattern. Nonvolatile memory devices manufactured using the method are also provided.
