In the second region, a second drain region and a second floating region are formed apart from each other. A first impurity region, a second impurity region, and a third impurity region are disposed in a common source region between the first and second regions of the substrate.

    摘要: A method of manufacturing a NOR-type mask ROM device includes forming a first gate electrode for an OFF cell and a second gate electrode for an ON cell on a semiconductor substrate of a first conductivity type. To code the mask ROM device, a plurality of source/drain regions is formed by implanting impurities of a second conductivity type, opposite the first conductivity type, into the semiconductor substrate adjacent only to one side of the first gate electrode and adjacent to both sides of the second gate electrode. To prevent misalignment of a bit line contact hole with a contact region, additional impurities are implanted only into a bit line contact region of the mask ROM device region. When a semiconductor device formed on the same substrate as the mask ROM device includes a double diffused region, additional implantation for both may be realized simultaneously.
