Nonvolatile memory device and method for manufacturing the same

摘要

The present invention discloses a nonvolatile memory device which can improve the data storage capacity without increasing the surface area of the device, and a method for manufacturing the same. The nonvolatile memory device comprises: a gate of a stack type structure formed on an active region of a semiconductor substrate; a source/drain formed in the substrate at both sides of the gate of the stack type structure; an interlayer insulating film formed on the substrate where the source/drain is formed and covering the gate of the stack type structure; a contact connected to the source/drain through the interlayer insulating film; a plurality of conductive patterns formed in the interlayer insulating film of the region not adjacent to the contact; and an electrode pad formed on the conductive patterns.
