ABSTRACT:
In a nonvolatile memory device and manufacturing method, the device includes cell transistors having sources and drains shared by cell transistors adjacent in a first direction, a floating gate confined to the respective cell transistors, and a control gate shared by cell transistors adjacent in a second direction, first plugged conductive layers formed in a long rod shape in the second direction so that sources of cell transistors adjacent in the second direction are connected with one another, second plugged conductive layers each connected with drains of the respective cell transistors, a common source line formed in a long rod shape in the second direction so as to be connected with the first plugged conductive layers thereon, a pad layer formed so as to be confined to the respective cell transistors on the second plugged conductive layers, and a bit line connected with the pad layer through a contact hole.
