Abstract:
1. A method of manufacturing a nonvolatile memory device, comprising: providing a semiconductor substrate including a cell region; forming first gate lines and second gate lines over the cell region of the semiconductor substrate, wherein the first gate lines are spaced from each other at a first width, the second gate lines are spaced from each other at a second width, and the first gate lines and the second gate lines are spaced from each other at a third width; forming first junction regions in the semiconductor substrate between the first gate lines, between the first gate line and an adjacent second gate line, and between the second gate lines by performing a first ion implantation process; and forming second junction regions in first junction region of the semiconductor substrate between the first gate lines and between a second gate line and an adjacent first gate line by performing a second ion implantation process, wherein the third width is wider than the second width, and wherein the third width is larger than a height of the first gate lines and the second gate lines.
