Abstract:
A mask read-only memory (ROM) device, which can stably output data, includes an on-cell and an off-cell. The on-cell includes an on-cell gate structure on a substrate and an on-cell junction structure within the substrate. The off-cell includes an off-cell gate structure on the substrate and an off -cell junction structure within the substrate. The on-cell gate structure includes an on-cell gate insulating film, an on-cell gate electrode and an on-cell gate spacer. The on-cell junction structure includes first and second on-cell ion implantation regions of a first polarity and third and fourth on-cell ion implantation regions of a second polarity. The off-cell gate structure includes an off-cell gate insulating film, an off-cell gate electrode and an off-cell gate spacer. The off-cell junction structure includes first and second off-cell ion implantation regions of the first polarity and a third off-cell ion implantation region of the second polarity.
