  • Patent number: 7443731
    Abstract: An operation scheme for operating stably a semiconductor nonvolatile memory device is provided. When hot-hole injection is conducted in the semiconductor nonvolatile memory device of a split gate structure, the hot-hole injection is verified using a crossing point that does not change with time. Thus, an erased state can be verified without being aware of any time-varying changes. Also, programming or programming/erasure is conducted by repeating pulse voltage or multi-step voltage application to a gate section multiple times.

    Abstract: A polysilicon film forming a memory gate interconnection and the like includes a part extending from a part positioned on one side surface of a control gate interconnection to a side opposite to a side where the control gate interconnection is positioned, and that part serves as a pad portion. A contact hole is formed to expose the pad portion. The height of a part of the polysilicon film that is positioned on one side surface of the control gate interconnection is set equal to or lower than the height of the control gate interconnection so that the polysilicon film forming a memory gate interconnection and the like does not two-dimensionally overlap the control gate interconnection. Therefore, a semiconductor memory device with increased process margin can be obtained.

  • Patent number: 7095074
    Abstract: Defects in element forming regions on which memory cells of a non-volatile memory are formed are to be diminished to reduce leakage current. End portions of element forming regions with non-volatile memory cells formed thereon are extended a length D by utilizing the region which underlies a dummy conductive film, whereby a stress induced from an insulating film which surrounds the element forming regions is concentrated on the extended region. As a result, defects do not extend up to the regions where memory cells are formed and therefore it is possible to reduce leakage current in the memory cells.

  • Patent number: 7015090
    Abstract: At least not less than one capacitor formation trench providing an uneven surface is formed on the surface of a capacitor formation region. Thus, the surface area of a capacitor is increased, which enables improvement of the capacitance of the capacitor per unit area. Further, by forming the capacitor formation trench and an element formation trench that are formed in the surface of the semiconductor substrate by the same step, it is possible to simplify the manufacturing process. Whereas, a dielectric film of the capacitor in the capacitor formation region and a high-voltage gate insulating film in a MISFET formation region are formed by the same step; alternatively, the dielectric film of the capacitor in the capacitor formation region and a memory gate interlayer film between a polysilicon layer and a polysilicon layer in the memory cell formation region are formed by the same step.
